INTRODUCTION:

The name "Phytosome" alternatively referred to as "herbosome" is made up of the terms "phyto" and "some" which pertain to both plant-related and cell-resembling attributes.These are also recognized as phyto-phospholipid complexes. Phospholipids and plant chemicals, such as phosphatidylcholine (PC), phosphatidylethanolamine, phosphatidylserine, soy-derived phospholipid, and egg-derived lecithin, are combined to form phytosomes. Plant extracts or hydrophilic phytochemicals in phospholipids form phytosomes, a novel vesicular drug delivery system¹. The active ingredient is a part of the membrane of the phytosome². With a structure similar to a liposome, phytosomes are a novel lipid-based delivery technology that can be utilized to entrap different phytoconstituents with polyphenolic bases to improve their absorption when delivered¹.

To improve the miscibility of bioactive phytoconstituents in lipid-rich barriers and address their low bioavailability, one of the emerging nanotechnologies is called phytosomes^1,3. Well-known biocompatible nanocarriers called phytosomes can be used to make phytopharmaceuticals more soluble and permeable in a variety of novel drug delivery methods^{1, 4}. In contrast to liposomes, phytosomes contain bioactive substances either within the core orifice or in the spaces between layers of the membranous shell. The bioactive substance is a crucial component of the micelle in phytosomes, where molecules are chemically bonded to the hydrophilic heads of the phospholipids. Phytosomes are used to transport both water and lipid-soluble chemicals, whereas liposomes are employed to carry solely water-soluble compounds¹. Phytosomes containing cholesterol are regarded as effective carriers to enhance the rate of permeation through cell membranes while also safeguarding the carried active metabolites from environmental oxidative stress, whether they are natural or synthetic antioxidants, within the context of human biological conditions. The physicochemical characteristics and penetration rate of phytosomes or carrier particles can be enhanced by utilizing natural polymers, such as polysaccharides for coating. This method offers a modified release profile, improved adhesion, improved payload uptake, and increased stability during storage and handling⁵. When coupled with cancer-specific antibodies like anti-HER2, transferrin, and folate, liposomes and phytosomes exhibit heightened capacity to recognize and bind to cancer cells with enhanced effectiveness. Phytochemicals can be transported by targeted nanocarriers and can facilitate their internalization into the intended target cells. Phytochemicals' ability to heal wounds has been increased by liposomes and phytosomes⁶. The stability and bioavailability of phytoconstituent encapsulated systems may be affected by the particle size of phytosomes, which is highly significant⁷. In comparison to other lipid-based systems like liposomes, phytosomes are said to offer better physical stability, higher entrapment efficiency, and lesser vulnerability to drug leakage or expulsion from the delivery system⁸. Unlike liposomes, phytosomes are the result of a chemical interaction that occurs between a phospholipid molecule and a polyphenolic component, achieved either through the establishment of a hydrogen bond or through the influence of van der Waals attraction⁹.

Riva A, et al performed a study in which they examined a blend of botanical compounds, including bergamot phytosome and a dried extract from artichoke leaves in subjects with mild hypercholesterolemia that showed poor response. The result seen was an enhancement in lipid profile with a significant decrease in total and low-density lipoprotein and an increase in high-density lipoprotein indicating synergism¹⁰. The scientist also worked on the absorption profile of quercetin from the quercetin phytosome using food-grade lecithin. The oral administration produced a 20-fold increase in plasma levels attained and improved bioavailability¹¹.

Thus this review highlights the introduction, structure, types, composition, advantages, disadvantages, manufacturing process involved, and pharmaceutical approach along with the future scope of phytosomes in the domain.

STRUCTURE OF PHYTOSOME:

Figure 1: Structure of Phytosome¹

PHYTOSOMES A BETTER DELIVERY SYSTEM COMPARED TO LIPOSOMES:

A complex involving chemical interactions is established between the polar compounds and the polar heads of the phospholipid bilayer in phytosomes as opposed to liposomes, which trap polar plant extracts in the aqueous compartment and surround them with the phospholipid bilayer. Because of this dispositional difference, phytosomes store plant extract more effectively than liposomes¹². These are intrinsic conjugations, rendering them more potent and enduring carriers compared to liposomes.

To generate sealed vesicles, liposomes encapsulate bioactive materials within either the core of the phospholipid globule (hydrophilic encapsulants) or the phospholipid bilayer (lipophilic encapsulants). Contrarily, the hydrophilic ends of phospholipids and bioactive chemicals form hydrogen bonds to form the majority of the structure of the phytosomal complex. When dispersed in the aqueous phase, phytosomes form nano-size micelles (about 100 nm, somewhat smaller than liposomes)⁶. The bioactive substance is a crucial component of the micelle in phytosomes, where the molecules are bonded chemically to the polar heads of the phospholipids¹³. Phytosomes are used to convey both water and lipid-soluble chemicals across cell membranes, whereas liposomes are utilized to carry solely water-soluble compounds. To increase the miscibility of bioactive phytoconstituents in lipid-rich barriers and overcome their low bioavailability, phytosomes are one of the emerging nanotechnologies¹.

COMPONENTS OF PHYTOSOMES:

Phospholipids:

Based on their backbone structure, phospholipids can be categorized as glycerophospholipids and sphingomyelins. Phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylserine (PS), phosphatidic acid (PA), phosphatidylinositol (PI), and phosphatidylglycerol (PG) are classified as glycerophospholipids. Out of these, the primary phospholipids used to form complexes featuring a hydrophilic head group and two hydrophobic hydrocarbon chains are PC, PE, and PS. Among them, PC is the most commonly employed phospholipid for preparing phospholipid complexes. The advantageous features of PC include its amphipathic nature, which grants it moderate solubility in both lipid and aqueous environments. Furthermore, PC is noted for its strong biocompatibility and minimal toxicity due to its pivotal role in cell membranes. It has been observed that PC molecules have therapeutic effects in the treatment of liver disorders and exhibit hepatoprotective properties as well¹³.

Phytoactive constituents:

Instead of focusing on in vivo activities, researchers typically characterize the active ingredients of herbal extracts derived from robust in vitro pharmacological activities. These chemicals primarily consist of polyphenols. Hesperidin, as a physiologically active polyphenolic compound found in plants, exhibits a predilection for the aqueous environment and is incapable of traversing biological membranes. Others, like curcumin and rutin, have significant lipophilic characteristics and do not dissolve in gastrointestinal fluids that are watery. Hydrophilic polyphenols from the aqueous phase can also penetrate membranes more easily. These phyto-phospholipid complexes also enhance the water solubility of hydrophobic polyphenols. Furthermore, the formation of complexes can provide protection for polyphenols from being destroyed by outside processes like hydrolysis.

Solvents:

Researchers have employed a variety of solvents as the medium for the reaction while creating phyto-phospholipid complexes. In recent times, protic solvents like ethanol and methanol have effectively supplanted aprotic solvents previously employed for the production of phyto-phospholipid complexes. These aprotic solvents included aromatic hydrocarbons, halogen derivatives, methylene chloride, ethyl acetate, or cyclic ethers. In a liquid with a reduced dielectric constant, phytosomes interact. Recent studies have employed the supercritical fluid (SCF) technique to manipulate the size, shape, and morphology of the target material. An emerging SCF technology that proves effective in producing micronic and submicronic particles with precise size and size distribution control is the supercritical anti-solvent process (SAS). To reduce the solubility of the solute in the solvent, this method utilizes a supercritical fluid, often carbon dioxide (CO₂), as an anti-solvent.

Ratio:

The stoichiometric proportion of active components to phospholipids plays an important role in the formulation of phytosomes. Synthetic or natural phospholipids are commonly employed in the formation of phyto-phospholipid complexes, and they interact with the active constituents in a molar ratio ranging from 0.5 to 2.0. A 1:1 stoichiometric ratio is considered the most efficient for producing phospholipid complexes. To make quercetin-phospholipid complexes, for instance, Lipoid S 100 and quercetin were mixed in a 1:1 molar ratio. Various stoichiometric ratios between the active components and the phospholipids have, nonetheless, been utilized. Using several stoichiometric ratios of 1:5, 1:10, and 1:15, Maryana et al., created silymarin-phospholipid complexes. They discovered that the complexes with a stoichiometric ratio of 1:5 had the greatest physical characteristics and the largest loading capacity of 12.18% ± 0.30%².

MANUFACTURING PROCESS OF PHYTOSOMES:

Solvent evaporation/thin film hydration method:

One commonly used traditional approach for creating phospholipid complexes is the solvent evaporation method. In this method, phosphatidylcholines and active components are blended in a round-bottom flask and dissolved in an appropriate solvent by heating at a constant temperature for a defined period. The resulting complexes are obtained by removing the solvent under vacuum conditions. The solvent evaporation procedure used to create phytosomes containing a complex of mitomycin C (MMC) and soybean phosphatidylcholine (SPC) involves the mixing of 12.5 mL of tetrahydrofuran (THF), 10 mg powder of MMC, and SPC 30 mg. This mixture was then subjected to rigorous stirring in a water bath at 40 °C for 4 h, resulting in a clear magenta mixture. Subsequently, the THF solvent was removed using a rotary evaporator and vacuum rotary evaporation^1-2,5,24.

Anti-solvent precipitation method:

The second most commonly used technique for preparing phytosomes involves a specific procedure. In this method, lawsone and soy lecithin are mixed and refluxed in dichloromethane, keeping the temperature below 60 °C. After refluxing, precipitate forms, n-hexane is introduced into the mixture, and then it is left overnight within a vacuum desiccator. In another method, icariin phytosomes (ICA) were prepared using an anti-solvent precipitation method combined with refluxing. Accurately measured quantities of ICA and Phospholipon^® 90H were dissolved in dichloromethane. The solution was refluxed at specific temperature and duration parameters outlined in the experimental design, resulting in a concentrated solution (about 5 mL). Both of the phytosomal formulations were dried through lyophilization for 72 h. The dried complex is then stored in an airtight amber glass container at 4° C for future use^1-3,25-26.

Freeze drying or lyophilization method:

In this process, phytosomes are meticulously prepared through the utilization of freeze-drying or lyophilization techniques. Specifically, these techniques are employed to synthesize diosmin phytosomes (DSN). The procedure commences with the complete dissolution of diosmin (DSN) in dimethylsulphoxide (DMSO). Subsequently, the resultant DSN solution is combined with an SPC solution, which is dissolved in t-butyl alcohol. The mixture is subjected to 3 h of continuous stirring on a magnetic stirrer until complex formation is achieved.

The formed complex is then meticulously isolated through a lyophilization process. Initially, vials containing the complex are cryogenically frozen for 4 h at a temperature of -80 °C. Afterward, these vials are moved to a Cryodos-50 lyophilizer with the condenser temperature adjusted to 70°C. The initial lyophilization phase is conducted within a day while sustaining a pressure of 40 mbar and a shelf temperature of 40°C. Following this, an additional day is dedicated to the secondary drying process, which is conducted at a temperature of 25 °C.

Upon completion of the drying phases, the resulting sample is extracted from the freeze dryer and carefully placed within a desiccator for storage. It is crucial to emphasize that the efficiency of these techniques is significantly impacted by various critical factors, including the choice of phospholipid, the ratio of the drug (diosmin) to lipid, and the selection of an appropriate co-solvent. These considerations play a pivotal role in the successful formulation and bioavailability of the diosmin phytosomes^{1-3,
5, 24-26}.

EVALUTION OF PHYTOSOME:

Visualization:

Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM) can all be used to study the morphology of phytosomes^{1, 27-28}.Analyzing the morphology of phytosomes surfaces frequently reveals the trapping mechanisms and any pollutants that may be present there. Through the examination of surface morphology, it is frequently possible to identify entrapment behavior, surface properties, and the existence or absence of contaminants on the surface¹.

Transmission electron microscopy:

A sample drop is deposited onto a copper grid in the form of a thin film. The excess is cleared and the film is stained with uranyl acetate and further dried at room temperature and later TEM is performed^{2,
9, 23, 29}.

Particle size:

It is studied using a particle size analyzer for coated as well as uncoated phytosome^5,30. Even dynamic light scattering can be used for evaluation^{1, 9, 23,31-34}.

Zeta Potential:

Zeta potential is the charge of phytosome in emulsion. It may be negative, positive, or neutral depending on the composition of the phytosome. Zeta potential tends to repel each other more strongly, resulting in better dispersion, stability, and reduced aggregation. It can be quantified using Doppler velocimetry, a zeta sizer, and other techniques, in a laser beam to measure the velocity or linear or vibrational motion of phytosome emulsions ^35-36.

Entrapment efficiency:

Entrapment efficiency refers to the percentage of the drug that is effectively encapsulated within the micelle or nanoparticle. It can be assessed using the ultra-centrifugation method. To determine the percentage of drug entrapment, one can extract the phytosomes intended for a particular application. This involves using appropriate solvent systems and centrifuging them for either a shorter duration or an extended period at higher rpm values. Subsequently, the drug content in the supernatant can be assessed, typically through UV-visible spectroscopy or high-performance liquid chromatography.For vitexin, the entrapment efficiency of phytosomes was gauged by assessing the proportion of vitexin that remained unencapsulated. Following vacuum evaporation, the phytosomes were rehydrated with distilled water and then filtered. The total phenolic content of the filtered solution was analyzed as the total phenolic content at the surface of the phytosome^{30, 37}.

Percent entrapment efficiency can be calculated using the formula,

Entrapment efficiency (%) = (E_O – E_I) /E_O * 100

Where E_O is the total phenolic content of vitexin added to the preparation of the phytosome and E_I is the total phenolic content at the surface of the phytosome

Vesicle stability:

The stability of phytosome vesicles concerning alterations in size and shape over time can be evaluated through a range of techniques. DLS and SEM are very useful for measuring the vesicle size whereas TEM and SEM are employed to monitor structural alterations in phytosomes ^1,
38.

Transition temperature:

Differential scanning calorimetry (DSC) is a potent analytical method that offers valuable insights into various interactions. During DSC analysis, these interactions are revealed through several observable changes, including disparities in transition temperatures, the emergence and disappearance of distinctive peaks, shifts in melting points, and alterations in peak areas. A particularly informative application of DSC involves comparing physical mixtures with phyto-phospholipid complexes. Such comparisons often unveil characteristic peaks that differ significantly, indicating substantial interactions between the active ingredients. These interactions can encompass various aspects, including the involvement of the two fatty chains of phospholipids and the polar component of phospholipids, which constrain free rotational movements¹.

Drug release:

Continuous flow, sample and separate techniques, in situ procedures, and membrane diffusion strategies (dialysis, microdialysis, fractionalization, and reverse dialysis) are the most often used traditional ways to measure the release rate of active compounds [1]. Analytical techniques to measure the drug release are gel electrophoresis, dialysis, enzymatic tests, HPLC, UPLC, UV-Vis, field flow fractionation, sample-and-separate methodology, the in-situ method, and continuous flow are some examples of analytical techniques^{35, 39}.

Using the dissolving test device USPXXIII at 50 rpm, the phyto-phospholipid complex's in-vitro drug release was tested. The temperature was 37 °C with 900 ml of 6.8 phosphate buffers as the dissolving medium. 5 ml of aliquots were filtered using 0.45 mm Whatmann filter paper and its absorbance was measured to calculate the drug content⁴⁰.

Fourier transformation infrared spectroscopy (FTIR):

An FTIR spectrometer was employed to examine the interaction between the phytoconstituent and phosphatidylcholine⁴¹.

Differential scanning calorimetry (DSC):

The specimens were subjected to heating from 0 to 300 °C at a rate of 100 °C per minute in a nitrogen environment (60 milliliters per minute). The extract-phospholipid complex's peak transition initiation temperature was noted⁴².

Scanning electron microscopy (SEM):

The surface structure of phytosomes was investigated via scanning electron microscopy (SEM). In this process, phytosome samples were affixed to one side of double-sided adhesive tape and coated with a layer of gold under vacuum. The SEM was run at 15 kV with 500 and 10,000x magnification^40,
43.

Stability studies:

Phytosomal stability is a vital componentthat plays a pivotal role in the effective formulation of a carrier system. Stability investigations are conducted to examine the changes in phytochemical composition within phytosomes during storage and overall distribution. Stability can be assessed by monitoring the mean vesicle size, zeta potential, size distribution, and entrapment efficiency over some time¹. Phytosomal stability is another vital component in the appropriate design of a carrier system.Stability studies are carried out to look at the phytochemical modifications of phytosomes throughout storage and general circulation³⁵.

APPLICATIONS OF PHYTOSOMES INTHE PHARMACEUTICAL INDUSTRY:

A unique medication delivery system called phytosomes increases the bioavailability of plant-based ingredients including phytoconstituents and herbal extracts.

Depression therapy:

The utilization of a phytosomal formulation, incorporating Annona muricata water extract, aims to boost its permeation through the blood-brain barrier (BBB) and amplify its antidepressant-like impact by inhibiting monoamine oxidase B (MAO-B)³⁵.

Cerebral ischemia:

Rutin was encapsulated within a phospholipid structure and was assessed for its bioavailability in an animal model of cerebral ischemia. Rats received an oral phytosomal formulation comprising an ethanolic extract of Ashwagandha (Withania somnifera) root one hour before the onset of ischemia and again six hours after reperfusion. This intervention led to a noteworthy reduction in cerebral infarction in the rats³⁵.

Migraine:

When administered twice daily, the blend of ginkgo biloba terpenes phytosome (60 mg), vitamin B2 (8.7 mg), and coenzyme Q10 (11 mg) demonstrated favorable effects on the frequency of migraines³⁵.

Cancer:

Plants harbor compounds like flavones, isoflavones, flavonoids, anthocyanins, coumarins, lignins, catechins, and isocatechins, all of which possess antioxidant properties and hold promise in combatting cancer¹.Quercetin phytosomes with scorpion venom were developed by Alhakamy N. A., et al., for the treatment of breast cancer. He modified the phytosomes and tested their efficiency against MCF-7 cells. Quercetin phytosomes enhanced doxorubicin's efficacy in preventing the spread of the MCF-7 human breast cancer cell line.Cell cycle studies showed that the QRT (Quercetin) formula therapy considerably halted the cell cycle progression at the S phase. Breast cancer treatment with QRT (Quercetin) phytosome formulation is effective.According to Sabzichi M, et al., doxorubicin sensitivity in MDA-MB 231 cells was increased when luteolin was used as an advanced nanoparticle carrier in phytosomes. Researchers created nanophytosomes of luteolin to increase its bioavailability in breast cancer cells. Aloe vera extract is combined with phospholipids in a new phytosome-loaded gel that was produced by Manikkampatti, et al., The MCF-7 cell line is inhibited by aloe vera that has been loaded with phospholipids, and this impact is particularly concentration-dependent¹.Ibrahim et al. conducted a study in which they investigated the use of curcumin and phosphatidylcholine for treating solid tumors in the mammary glands of patients¹.To increase cytotoxicity and ability to induce apoptosis in ovarian cancer cells, Alhakamy NA, et al., created optimized icariin (ICA) phytosomes¹.Thymoquinone (TQ) loaded soy-phospholipid-phytosomes were also created by Alhakamy, et al., and proven their anticancer effectiveness against human lung cancer cells¹.A strong soy isoflavone called genistein is used to treat hepatocellular carcinoma (HCC). HCC is the liver malignancy that cause cancer. Genistein, one of the main components of soybeans, is a natural anti-cancer agent⁴⁴.Gen-phytosomes might be a potentially effective strategy for treating liver cancer¹.Patients received Meriva^®, a proprietary form of curcumin complexed with phospholipids, along with gemcitabine for the treatment of pancreatic cancer³⁵.

Rheumatoid arthritis:

Leflunomide (LEF) and curcumin (CUR) were co-loaded with phytosomes to enhance the clinical effectiveness of RA treatment. LEF shows the immunomodulatory effect. The biological effects of curcumin (CUR) are diverse and include anti-inflammatory, hepatoprotective, antibacterial, antidiabetic, analgesic, and anticarcinogenic properties⁴⁵.

Cosmetics benefits:

Glycosides and flavonoids are water-soluble compounds, with flavonoids being the bioactive component. Many natural flavonoids from plants, like glycyrrhizic acid and silymarin, provide beneficial cosmetic benefits when used on the skin. Nevertheless, it's worth noting that certain plant flavonoids can lead to various health issues, including edema, discomfort, inflammation, and susceptibility to bacterial and fungal infections. The calyx of the Nyctanthes arbor-tristis flower contains crocin, an apocarotenoid compound that serves as the primary constituent found in the saffron stigma. Consequently, it represents a cost-effective alternative to saffron, offering both medicinal and cosmetic benefits⁴⁶.

Wound healing:

Species within the Brassicaceae family are known to contain sinigrin, a compound with antibacterial, anti-inflammatory, and anticancer properties. Both DSC and FTIR investigations provided supportive evidence for the intricate formation of the sinigrin-phytosome complex²⁵. Instead of focusing on its wound-healing potential, scientists conducted a study to examine sinigrin's effects on HaCaT cells. Specifically, they evaluated the impact of sinigrin as well as the sinigrin-phytosome complex on wound healing in HaCaT cells³⁵.

Inhibit tumor growth:

Zhenqing Hou and colleagues developed phytosomes containing Mitomycin (MMC) C in conjunction with soybean phosphatidylcholine. The creation of these phytosomes involved a combination of solvent evaporation and nanoprecipitation methods to produce proficient drug delivery systems for MMC. Notably, the MMC-loaded phytosomes exhibited more potent and dose-dependent suppression of tumor growth compared to free MMC, all while avoiding weight loss¹.

Hepatoprotective:

Silymarin, a phytochemical derived from the Silybum marianum plant, is recognized for its hepatoprotective qualities. Nonetheless, its utilization can at times be constrained by its inadequate water solubility and restricted oral bioavailability. The study aims to investigate the potential of phospholipid-based phytosomes in enhancing the oral bioavailability of silymarin^44-46.

Erythema:

As reported by Yasmiwar Susilawati and their team, the utilization of a phytosomal drug delivery system led to notable enhancements in the performance of quercetin. These improvements encompassed a noticeable reduction in erythema, decreased redness, itching, and inflammation, improved skin layers, increased hydration, and enhanced solubility and absorption of quercetin¹.

CONCLUSIONS:

The phytosomes are biocompatible nanocarriers that can make phytopharmaceuticals more soluble and permeable in a variety of NDDS. The hydrophilic phytochemicals or plant extracts are included in phytosomes, an innovative and emerging vesicular drug delivery technology to boost their bioavailability and absorption while circumventing the shortcomings and potential side effects associated with traditional herbal extracts. Phytosome characterization and formulation methodology are well known. While phytosomes have several advantages, including improved stability, bioavailability, and hepatoprotective effects, they also have some disadvantages, including the speed with which phytoconstituents are removed from them and their pH sensitivity. After the creation of a successful formulation, safety confirmation presents the biggest challenge. Through the amalgamation of both organic and synthetic anti-cancer medications within nano-phytosomes, oral bioavailability experiences a significant enhancement, while simultaneously retarding tumor growth. The utilization of phytosome technology in the nano-formulation of nutraceuticals has the potential to revolutionize the utilization of hydrophilic plant compounds in cancer treatment. Future research may have revolutionary results when phytosomes or medication are combined with other phytochemicals in a nano-vesicle.

MARKET POTENTIAL:

The creation of a phytosome as a drug delivery system aims at improving the cost-effectiveness and sustainability of formulation. Phytosomal technology will have a great impact on the cosmetic market by the way it is giving efficient results in terms of skin-related issues. Phytosome technology involves the complexation of plant extracts with phospholipids, which enhances their bioavailability and absorption in the body. Phytosomes are effectively used in the treatment of cancer, which in addition, development and research can be the next big thing in medical history.With this newly created formulation tool, the utilization of phytosomes has redefined the importance of herbal components in contemporary drug-targeting strategies. Phytosomes as biodegradable substrates can be consumed risk-free and without any hesitation. It has numerous benefits and a wide potential to treat skin conditions. It can promote blood clotting and wound healing, and relieve burns and other skin diseases as well.It possesses the capability to stimulate blood clotting, expedite wound healing, and alleviate burns and various skin ailments. Furthermore, it improves the stability and enhances the skin penetration of phytochemicals. Nano-crystal gel formulations and self-micro-emulsifying drug delivery systems have been investigated to improve the delivery of topical application of phytochemicals. A key feature of phytosomal drug delivery lies in the fact that the materials necessary for phytosome formulation are primarily safe and efficient, rendering them suitable for large-scale industrial synthesis. The raw materials essential for phytosome preparation and production are readily accessible, easily obtainable, and can be extracted with ease.

FUTURE SCOPE:

Phytosomes are utilized in cosmetics and have evolved into a crucial tool in modern medicine. These innovative formulations have expanded their applications to address a range of ailments, including cancer, heart disease, inflammation, liver-related diseases, and more. Phytosomes have redefined the role of herbal ingredients in contemporary healthcare, not only for passive targeting but also for active targeting through the attachment of specific ligands and antigens to cellular structures. This versatility broadens the scope of diseases that can be treated, such as cancer, osteoarthritis, and rheumatism. Moreover, the advent of nanotechnology-based phytosomes has transformed drug delivery by addressing issues linked to lipid solubility and elevating the bioavailability of essential phytochemicals such as silybin, ginkgo, and polyphenols present in olive oil. Many phytochemicals have already found success in phytosome formulations, with the potential for others to follow suit. Combining phytosomes with other phytochemicals or incorporating them into nano-vesicles may yield synergistic effects, offering promising prospects in the pharmaceutical industry with the support of physicians and researchers. This presents an extensive opportunity to repurpose medications for various therapeutic applications. Phytosomes represent a valuable solution for enhancing the bioavailability of poorly absorbed natural extracts, thanks to established analytical methods and manufacturing processes. Their myriad advantages make them a preferred choice compared to conventional medicines. Moreover, the growing popularity of biocompatible, affordable, and safe natural products has spurred interest in this form of treatment. The straightforward manufacturing process encourages the rapid industrial-scale adoption of phytosomal technology. Various pharmaceutical companies have explored the advantages and biological effects of phytosome formulations, highlighting the enhanced bioavailability of polar phytoconstituents.It is encouraged for researchers to persist in their investigations, emphasizing standardized products' clinical research to demonstrate enhanced efficacy compared to unformulated components or extracts. With its capacity for controlled release systems, targeted delivery, and enhanced compound stability. Phytosomal technology stands as a promising approach for cosmaceutical products, promoting their effectiveness. Future research efforts that involve combining phytosomes with other phytochemicals or incorporating both medication and phytochemicals into nano-vesicles may yield a range of stimulating effects.
