A doctor from Institute of Botany, Chinese Academy of Sciences said in Weibo that Gynura divaricata contains pyrrolizidine alkaloid, which is hepatotoxic. People are advised not to eat this wild vegetable. He introduced that Gynura bicolor belongs to Compositae, Senecio and Gynura bicolor in taxonomy. In the last century, chemists found that pyrrolizidine alkaloid (PA) was widely found in Senecio plants. A large number of animal toxicity experiments proved that PA had strong hepatotoxicity and could lead to liver cirrhosis.

In addition, it has carcinogenic and teratogenic effects and can lead to primary pulmonary hypertension. Later, these alkaloids were also isolated from purple sweet potato. Toxicological analysis of purple sweet potato and several other Inula wild vegetables showed that the above-ground part of purple sweet potato had the strongest hepatotoxicity. Therefore, people are advised not to eat red phoenix vegetables.

In short, although there is no authoritative organization to ban the consumption of blood-skin vegetables!

However, people who love to eat blood kimchi should also eat it in moderation. After all, it may indeed cause liver damage. Experts say that frying with high fire may reduce its toxicity.
