What it’s for
- Marketed for testosterone or sexual function
Products sold under the Bulbine name, with species and extract sometimes unspecified.
Purpose, evidence and practical considerations.
Animal findings do not demonstrate a safe or effective human testosterone treatment. A personal report of abnormal liver tests is a safety account, not a controlled trial.
Confidence: unsupported
Animal work with B. natalensis reported liver and kidney toxicity signals; human safety and effective dosing are not established. Unknown species and extracts add uncertainty.
Claims about Bulbine natalensis extracts mainly come from laboratory and animal research. They do not establish the composition or effects of an unspecified Bulbine product.
The evidence on this page does not automatically apply to:
How people use it, with their schedules, context and original sources.
He stopped after an unfavourable change in liver enzymes.
These share a protocol with this intervention. This does not establish that they work together or are suitable alternatives.
