Abstract: A method of promoting nerve regeneration in a subject that includes administering to the subject a therapeutically effective amount of a composition that includes at least one therapeutically-active extract fraction of Centella asiatica. One example of making the extract fraction of Centella asiatica involves extracting Centella asiatica plant material resulting in an extract residue and successively fractionating the Centella asiatica extract residue with at least two eluants of increasing polarity.

Abstract: Embodiments of the present invention are directed to methods, apparatuses, and systems for the treatment of various skin conditions by delivery of piperine and/or a related structural analog of piperine (collectively referred to as piperine-based compounds) to an area of skin affected by a skin condition (e.g., vitiligo) in conjunction with irradiation of the affected area. Structural analogs of piperine include compounds such as THP, CHP, and RCHP. In various embodiments, irradiation of affected skin in conjunction with a piperine-based composition may result in stimulation of melanin synthesis by melanocytes which may induce pigmentation to a greater extent than with the use of the piperine-based compound alone.

Abstract: The present invention provides compounds of formula (I) and analogues or derivatives thereof for the treatment of skin conditions, such as Vitiligo, which are treatable by the stimulation of melanocyte proliferation and also for treating skin cancer.

Abstract: The present invention provides compounds of formula (I) and analogues or derivatives thereof for the treatment of skin conditions, such as Vitiligo, which are treatable by the stimulation of melanocyte proliferation and also for treating skin cancer. The compounds may also be used to cosmetically enhance the natural coloration of the skin.
