For skin conditions and pimples:

Grind 50 grams of leaf (15-20 leaflets) and add 1 liter (4 cups) of boiled water. Allow to settle for 12 hours. Wash affected area 2-3 times a day³.

For tinea (ringworm) and fungal growth (mycosis between fingers):

Wash injury with boiled water and soap. Properly wash leaf and crush it. Apply 5 grams (1 spoonful) of vegetal material on affected area of skin. Cover injury with dressing or clean cloth and replace 3-4 times a day.

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

According to published and other information:

Use for skin conditions, paño (pityriasis versicolor), pimples, ringworm and fungal growth (mycosis between fingers) is classified as REC, based on the significant traditional use documented in the TRAMIL surveys, toxicity studies, scientific validation and available published scientific information.

Should there be a notable worsening of the patient’s condition, or should symptoms persist for more than 5 days, seek medical attention.

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

TRAMIL Research²¹

The decoction from the fresh leaf (30%) (extract yield 13.6 mg/mL) was orally administered in a single dose of 6154 mg of vegetal material/kg of body weight (maximum volume 2 mL/100 g) to 6 Sprague Dawley rats (3 males and 3 females). The vehicle control was distilled water, given to the same number of animals of same characteristics. Twenty-four hour observation was performed for 14 days. There was no mortality and no adverse clinical signs were observed. Histopathological studies did not reveal any organic damage. The extract did not show any toxicity in this test.

TRAMIL Research²²

The aqueous extract from fresh leaf (20%) obtained through one-hour maceration was applied at a dose of 0.6 mL on an area of approximately 6 sq cm of the skin of 3 male New Zealand albino rabbits. After 4 hours, the patch was removed and the skin was checked for erythema and edema at 24, 48 and 72 hours. Given that no adverse clinical signs were observed, this use was classified as non-irritating.

Trabajo TRAMIL²⁷ (will be translated in 3rd Ed.)

La hoja fresca machacada, en aplicación tópica (0.6 g de material vegetal sobre piel afeitada en parche 4 x 3 cm durante 24 h), a rata Wistar (5 hembras y 5 machos), modelo de toxicidad aguda tópica, no provocó muerte, ni otros signos adversos durante los 14 días de observación. El estudio histológico de los órganos no mostró lesiones.

La tintura (maceración hidroalcohólica) (10:1) de hoja fresca administrada por vía oral al ratón Swiss albino (peso 18 a 22 g)mostró una DL₅₀ = 1459.32 mg/kg, según el método OECD-1987²⁶.(will be translated in 3rd Ed.)

The hydroalcoholic extract from leaf, administered orally and subcutaneously to mice (10 g of dried plant/kg) did not show evident signs of toxicity²³.

The hydroalcoholic extract (30%) of the foliage, administered at concentrations of 0.50 to 2.91 mg of total solids/mL in an in vitro assay with Aspergillus nidulans D30 (mitotic segregation) and at doses of 0.60, 1.21, 2.43 and 1313, 2625, 5250 mg/kg in the micronuclei induction test in vivo did not show mutagenic activity²⁴.

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

The leaf contains anthraquinones : aloe-emodin, chrysophanic acid, rhein^6-7, dihydroxymethylanthraquinone; tannins⁸, but no saponins⁹.

The fruit contains alkaloids¹⁰; the leaf and the flower do not contain leucoanthocyanins⁹.

The plant contains anthracene derivatives from aloe-emodin and rhein¹¹.

TRAMIL Research¹²

The aqueous (10%) and hydroalcoholic (95%) extracts from the fresh leaf, in vitro, were evaluated against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus andBacillus subtillis; Trichophyton rubrum, Aspergillus niger, Microsporum canis and Candida albicans. The aqueous extract did not inhibit the growth of any strain. The hydroalcoholic extract showed activity against all microorganisms studied, specifically, Trichophyton rubrum (100%),Microsporum canis (83%) and Aspergillus niger (51.6%).

The juice from the entire plant in vitro was inactive against Epidermophyton floccosum, Microsporum gypseum, Trichophyton rubrum, Candida albicans, Cryptococcus neoformans and Saccharomyces cerevisiae¹³.

The extract from the dried leaf in vitro showed antibacterial activity against Staphylococcus aureus (sensitive and penicillin-resistant strains) and Pseudomonas aeruginosa, isolated from secretions and from scraping patients’ skin. Other bacteria affected were: Streptomyces pyogenes, Escherichia coli, Klebsiella pneumoniae andSerratia marcescens¹⁴.

The infusion from the dried young leaf in vitro (5%) fully inhibited the growth of Trichophyton mentagrophytes, T. rubrum, Microsporum canis, M. gypseum and Epidermophyton floccosum inguinalis, but was not active against 2.5%¹⁵. The extracts (2.5 and 5%) did not inhibit the growth of Candida tropicalis, C. albicans or Cryptococcus neoformans¹⁶.

The dry hydroalcoholic extract (35%) from the leaf (10%) in vitro did not show activity against Neisseria gonorrhoea¹⁷.

The decoctions from the leaf, stem bark and root (1 mL)in vitro were inactive against Epidermophyton floccosum, Microsporum gypseum, M. canis andTrichophyton mentagrophytes¹⁵.

The dried ethanolic extract from the leaf in an ointment (10% polyethilenglycol base) revealed healing activity on rabbit skin¹⁸.

The aqueous extract from the leaf topically applied (at concentrations of 100, 90 and 80% depending on body area) in humans with pityriasis versicolor, eliminated the Malassezia furfur fungus that caused the disease¹⁹.

The hydroalcoholic extract (50%) from the dried leaf is claimed to have antihistaminic activity²⁰.
