Arjuna bark is one of the most important heart tonics in Ayurvedic medicine, used to treat all forms of heart disease. It reduces the heart-damaging culprits of inflammation (Pitta) and mucus (Kapha), and is strong enough to protect against scorpion stings. Arjuna bark contains a fair amount of triterpenoid saponins, and cooking tends to activate these chemicals (which is why saponin-rich Chinese ginseng root is always cooked). Looking at the traditional literature, we see that for more than 1,500 years TAM doctors have boiled arjuna bark in milk or ghee to make medicine, having patients ingest it daily for up to a year.
