Purchase a one pound package of Raintree's sustainably harvested pure avenca (Adiantum capillus-veneris) leaf powder - rich in active and beneficial phytochemicals that occur naturally in this plant. Chemical analysis of avenca reveals an array of compounds including triterpenes, flavonoids, phenylpropanoids, and carotenoids. Interestingly, despite its ancient use, there has been no specific research on avenca to isolate and test its chemicals for biological activities.* This plant has been milled into a fine powder which is suitable to stuff into capsules or to prepare your own teas, tinctures or extracts.
