  In the genus Orthosiphon (Lamiaceae), Orthosiphon aristatus, Orthosiphon pallidus, Orthosiphon thymiflorus, Orthosiphon stamineus are widely used in traditional medicine to prevent different diseases such as diabetes, kidney stone, edema, rheumatism, hepatitis, hypertensive and jaundice. A different variety of phytoconstituents has been isolated from the Orthosiphon species which include monoterpenes, diterpenes, triterpenes, saponins, organic acid and flavonoids compound. Antidiabetic, anti-inflammatory, antioxidant, hepatoprotective, analgesic and nephroprotective activities have been reported in the plant extract and phytoconstituents. Hence, the purpose of this review is to provide a comprehensive report about the Orthosiphon genus based on its toxicity in order to identify its therapeutic potential and future prospects for betterment of research.

  The oral delivery of hydrophobic drugs faces a major challenge because of the low aqueous solubility of such compounds. Approximately, 40% of new chemical entities exhibit poor aqueous solubility and present a major challenge to modern drug delivery system because of their low bioavailability. The availability of the drug for absorption can be enhanced by presentation of the drug as a solubilizer within a colloidal dispersion. Self-emulsifying Drug Delivery Systems (SEDDS), which are isotropic mixtures of oils, surfactants, solvents and co-solvents/surfactants, can be used for the design of formulations in order to improve the oral absorption of highly lipophilic drug compounds. The principal characteristic of these systems is their ability to form fine oil-in-water (o/w) emulsions or microemulsions upon mild agitation following dilution by an aqueous phase through the gastrointestinal tract for lipophilic drugs, which display dissolution rate-limited absorption. SEDDS may be a promising strategy to improve the rate and extent of oral absorption. This article gives an overview of the recent advances in the study of SEDDS and improvement of pharmacokinetic parameters of bioactives through SEDDS.
