Emblica officinalis (also referred to as Phyllanicaemblica or simply as Amla) is a herb from Indian medicine (Ayurveda) that has traditionally been used for the purposes of enhancing general vitality and cognition as well as promoting longevity; a goal similar to adaptogencompounds (although an adaptogenic effect has not clearly been demonstrated with Amla). There is very limited human evidence on Amla at this moment in time, but it appears to be very promising as it could lower blood glucose in both healthy persons and diabetics with a potency similar to the reference drug glibenclamide. In animal research, amla appears to be able to reduce triglycerides and better the cholesterol profile as well as benefit cardiovascular health (the heart and vessels themselves). Most of these actions are attributed to its antioxidant properties, which are partially derived from a high Vitamin C content but also from a large amount of tannin compounds that are also found in other potent antioxidants like camellia sinsensis (the plant that bears green tea catechins) and dimocarpuslongan. Along the more interesting but preliminary research is a hair growth promoting effect that exceeds that of minoxidil, and a longevity promoting effect in fruit flies that (while not directly compared against other agents) appears to be more effective than other nutraceutical options.
Unless otherwise specified, most benefits associated with emblica officinalis are from the fruits of the plant. The fruits themselves (dry weight) or their powder are taken in the dosage range of 1-3g daily with the higher part of this range being seen as more effective.
