Herbal Actions
Definition and Etymology

Asiatica refers to the plant’s native range across tropical Asia. In Sanskrit, the name mandūka-parnī (“frog-leaf”) describes the leaves’ resemblance to webbed frog’s feet. Another traditional name, Brahmi, connects the herb to the knowledge of Brahman, the universal consciousness, reflecting its revered use as a memory and meditation aid. In English, it is often called pennywort, since the rounded leaves resemble coins, and in Chinese medicine it is sometimes known as Ji Xue Cao (“blood herb”), referencing its use in promoting circulation and wound healing.
