**7. Feasibility of phytosome as novel vehicle for transdermal drug delivery**

Lipophilic drugs could be easily transfused by transdemal route which enhance the bioavalibility of phytoconstitutent. Drug would be delivered into systemic circulation by transdermal route transdermal route. Drug has to pass three different skin layers before reaching to systemic circulation. The outermost layer, *Stratum corneum* provides hindrances to such type of drugs delivery due to its lipophilicity. The Phytosomal form of phytoconstituents can pass this barrier easily and helps to deliver the phytoconstituents in systemic circulation. The research studies from two decades show the phytosome technology has enough potency to be used as novel carrier of Phytoconstituents. Phytosomal carrier has enough potency to be used transdermally for increasing bioavailability of Phytoconstituents [34, 35].
