For twisting and urethritis:

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

Any medicinal preparation must be preserved cold and used within the 24 hours.

According to published and other information:

Use for twistings is classified as REC, based on the significant traditional use (OMS/WHO)³ documented in the TRAMIL surveys.

Use for urethritis is classified as REC, based on the significant traditional use documented in the TRAMIL surveys and toxicity studies.

Due to the health risks involved with urethritis, an initial medical evaluation is recommended. The use of this resource can be considered complementary to medical treatment, unless it is contraindicated.

Should there be a notable worsening of the patient’s condition, or should urethritis or twisting persist for more than 3 days, seek medical attention.

Not for use during pregnancy or lactation.

TRAMIL Research¹⁴

The LD₅₀ of the aqueous extract (decoction) from the leaf, administered orally to Swiss UniValle albino mice (both male and female) was higher than 25 g/kg (observation period: 14 days). By intraperitoneal administration, the

LD₅₀ was 0.45 ± 0.007 g/kg (dose stated in grams of dried plant).

Trabajo TRAMIL¹⁵ (will be translated in 3rd Ed.)

Las partes aéreas frescas se aplicaron vía tópica (0.5 mL de una preparación de 1000 mg/mL de material vegetal sobre 5cm²), en el modelo de irritación dérmica en piel sana de 3 conejos New Zealand por 5 días consecutivos. No provocó ninguna alteración ni irritación durante ese periodo ni en los 11 días de observación.

There is no available information documenting the safety of medicinal use in children or in pregnant or lactating women.

The aerial parts contain alkaloids : choline, ephedrine, pseudo-ephedrine, ß-phenethylamine and derivatives, vasicin and derivatives⁴ and chryptolepine⁵; sterols : 22-dihydrocampesterol, cholesterol, 24-methylenecholesterol, ß-sitosterol, spinasterol, 22-dihydrospinasterol, stigmasterol and derivatives⁶

The leaf is rich in saponins⁷ and mucilages⁸.

Proximate analysis of 100 g of fresh leaf⁹: calories : 63; water: 80.24%; protein : 7.4%; fat: 1.4%; carbohydrate : 9.4%; fiber: 3.3%; ash : 1.6%; calcium : 466 mg; phosphorus: 58 mg; iron : 5 mg; carotene : 6050 µg; thiamine : 0.22 mg; riboflavin : 0.47 mg; niacin : 2.10 mg; ascorbic acid : 90 mg.

The tincture from the dried leaf (10 g in 100 mL of ethanol) in vitro (30 µL/disk) was inactive against strains of Neisseria gonorrhoeae¹⁰ and Candida albicans¹¹.

The methanolic extract from the leaf (1 g/mL) and the chloroform extract from the root (1 g/mL) were active in vitro Staphylococcus aureus, S. cerevisiae andEscherichia coli¹².

The sterol fraction from the fresh entire plant in vitro showed antibacterial activity against Escherichia coli, Staphylococcus albus,S. aureus, (0.5 mg/mL), and against Klebsiella spp and Pseudomonas pyocyanae (1 mg/mL)¹³.
