Rating (out of 5): 1

Earthworm (commonly referred to as "Di Long" in Traditional Chinese Medicine) has been used traditionally in several Asian medical systems for a variety of conditions, including external bleeding. Historical records and classical TCM texts document its use as an ingredient in topical formulations, often combined with other herbs, to help stop bleeding from wounds or injuries. The rationale in traditional practice often centers on the earthworm’s perceived effects on blood circulation and its ability to “cool the blood” and “resolve stasis,” which, according to TCM theory, can contribute to hemostasis (the stopping of bleeding).

However, there is very limited scientific research specifically validating the external use of earthworm extracts or preparations for treating bleeding. Most modern studies on earthworm extracts focus on their anti-inflammatory, antimicrobial, or fibrinolytic (clot-dissolving) properties, rather than direct hemostatic (bleeding-stopping) effects. While some laboratory studies have identified bioactive components in earthworms, such as lumbrokinase, these are mainly investigated for cardiovascular conditions rather than topical bleeding. Therefore, the support for its use in treating external bleeding remains primarily traditional, with minimal direct scientific evidence.
