The extract and fractions yielded mainly fatty acids, flavonoids, sesquiterpenoids, and products of chlorophyll breakdown. RAW264.7 cells exposed to GP extract and fractions showed significantly high proliferation and weak cytotoxic effect on macrophages. The extract and fractions may act as immunomodulators, as they induced promising proliferation of macrophages. (73)
• Anthelmintic / Leaves: Study evaluated the anthelmintic activity of crude extract of G. procumbens leaves against adult earthworms, Paramphistomum cervi. The ethanol extract exhibited dose-dependent anthelmintic activity in measures of paralysis time and death time. (74)

Buyers beware
• Ashitaba has been getting a lot of press, being touted as the new "miracle" herb.
However, a lot of potted "ashitaba" being sold locally from roadside herbal gardens and mall stalls, intentionally or unintentionally, is actually Sabungai rather than ashitaba (Angelica keiskei). (See Ashitaba)
