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.

La planta entera fresca, se aplicó vía tópica (0.5 mL de una preparación de 333.33 mg/mL de material vegetal sobre 5 cm2)en el modelo de irritación dérmica en piel sana de 3 conejos por 5 días consecutivos. No provocó ninguna alteración ni irritación durante el periodo de 11 días de observación.

There is no available information documenting the safety of medicinal use in children or in women during pregnancy or while breast feeding.

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.
