inflammation:

entire plant, natural, applied locally¹

For edema and inflammation:

There is no available information establishing a means of preparation and dosage other than that referred to by traditional use.

According to published and other information:

External use for edema and inflammation is classified as REC, based on the significant traditional use (OMS/WHO)² documented in the TRAMIL surveys.

For topical application, strict hygiene measures should be observed in order to avoid contamination or additional infection.

Should there be a notable worsening of the patient’s condition, or should edema or inflammation persist, seek medical attention.

TRAMIL Research⁴

The aqueous extract (1:1) from the entire plant, applied locally to New Zealand albino rabbits, UniValle strain, in groups of 9 animals each, using the Draize method modified by Finkelstein, did not induce any local alterations indicative of toxicity.

TRAMIL Research⁴

The aqueous extract (decoction 1:1) from the entire plant, in local application to the paw of albino rats (3 experimental groups and one control group, with five animals each), using the carrageenan-induced paw edema method, showed significant anti-inflammatory activity, comparable to the effects of dexametasone.

The ethanolic extract (1:5) from the fresh aerial parts did not show antibacterial activity in vitro⁵.
