Crassocephalum crepidioides, also called ebolo, thickhead, redflower ragleaf, or fireweed, is an erect annual slightly succulent herb growing up to 180 cm tall.

Its fleshy, mucilaginous leaves and stems are eaten as a vegetable, and many parts of the plant have medical uses.

However, the safety of internal use needs further research due to the presence of plant toxins.

[3] Crassocephalum crepidioides contains the hepatotoxic and tumorigenic pyrrolizidine alkaloid, jacobine.

[4][2] However, in another study, it is shown that the antitumor activity and macrophage nitric oxide produce action.
