Source-derived summary

Crassocephalum crepidioides, also called ebolo, thickhead, redflower ragleaf, or fireweed, is an erect annual slightly succulent herb growing up to 180 cm tall. Its use is widespread in many tropical and subtropical regions, but is especially prominent in tropical Africa. 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.

Ecology

The species is invasive in New Caledonia.

Toxicity

Crassocephalum crepidioides contains the hepatotoxic and tumorigenic pyrrolizidine alkaloid, jacobine. However, in another study, it is shown that the antitumor activity and macrophage nitric oxide produce action.

Editorial summary

The public source identifies “Crassocephalum crepidioides” as species of plant. This brief keeps that definition visible, then builds a research path around Crassocephalum, crepidioides and species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 112-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Crassocephalum, crepidioides and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Crassocephalum crepidioides”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 19, 2025. The linked authority identifier is Q1027615. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
