boil:

ganglionar inflammation:

The fruit ofCapsicum annuum is widely used for human consumption.

TRAMIL research28

For boils and ganglionary inflammation:

Wash injury with boiled water and soap, apply 2-4 grams of leaf to affected area.

Note: The popular practice of greasing in fat probably facilitates extraction of the active principle with the rubefacient effect -i.e. capsaicin-, but it carries the risk of overadded infection.

According to published and other information:

The use for boils and ganglionary inflammation is classified as REC, based on the significant traditional use (WHO)4 documented in the TRAMIL surveys.

Do not apply leaf for more than three minutes after local erythema (reddening) appears (normal reaction).

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

Self-medication should not be used in cases of boils or carbuncles on the face or neck where there is a risk of septicemia.

Adverse interaction with barbituric medicines has been documented, therefore ingestion of any plant part should be avoided by people taking these or other medicines metabolized in the liver.

The fruit powder may cause reactions of skin hypersensitivity.

TRAMIL Research30

The fresh leaves (0.6 g vegetal mass in hot vegetal oil) were administered topically (patch with 0.6 mL on 6 sq cm of shaved skin) to New Zealand rabbits (3 females), in Draize’s test. There was no edema or erythema during 72 hours of observation. 

TRAMIL Research31

The fresh leaves in hot oil were administered topically (patch of 0.6 g of vegetal mass on shaved skin, 4 x 3 cm, during 24 hours) to Wistar rats (5 females and 5 males), in the topical acute toxicity test. There was no mortality. No adverse sign was detected during 14 days of observation. There was no histological damage of organs. 

The hydroalcoholic extract (1:1) from the aerial parts by intraperitoneal administration to mice showed an LD50 = 0.375 g/kg19.

The aqueous and methanol-chloroform (2:1) extracts of the fruit with a concentration of 100 mg/plate did not show mutagenic activity in the Ames test with TA98 and TA100 strains, with and without metabolic activation20.  The ethanolic extract (95%) with a concentration of 1.85 mg/plate, in the same experimental model with TA98 and TA1535 showed mutagenic effects in strains with metabolic activation21.

The ethanolic extract from the fruit by intraperitoneal and oral administration to mice (200 mg/kg) maximized the action of barbiturics22.

The fruit may cause slight gastric irritation23 and at high doses may even lead to ulcers24.

The fruit powder in contact with the skin of exposed workers has caused sensitization25.

Topical creams containing capsaicin, available in 0.025% and 0.075% concentrations26, have induced local burning sensation and may lead to allergic reactions27.

Species of the Capsicum genus administered orally may inhibit the hepatic microsomal enzyme system.  Consequently, due care should be exercised if taken jointly with barbiturics, due to an acute poisoning risk22. (e n:  this enzyme system blockage will apply to the majority of medicines that are normally metabolized in the liver, for example the nifedipine group.)

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

The leaf contains saponins: capsicoside5; phenylpropanoids: chlorogenic acid6; flavonoids: cynaroside, luteolin glycosides7; steroidal alkaloids: solanine5.

The fruit has been extensively studied and contains, among other components: carotenoids, Vitamin C; amides: capsaicin and derivatives8.

Proximate analysis of 100 g of fruit9: calories: 289; water: 9.5%; proteins: 14.8%; fats: 13%; carbohydrates: 55.7%; fibers: 20.9%; ash: 7%; minerals: calcium: 177 mg; phosphorous: 345 mg; iron: 23.6 mg; sodium: 34 mg; potassium: 2344 mg; carotene: 36362 µg; thiamine: 0.64 mg; riboflavin: 1.74 mg; niacin: 15.32 mg; ascorbic acid: 71 mg.

TRAMIL Research29

The crushed fresh leaves or its juice, in vitro (0.1 g crushed material or 100 µL of juice/well), did not show any activity against Staphylococcus aureus(ATCC15006).

The ethanolic extract (80%) from the dried leaf (0.5 mL/plate) showed antifungal activity on Trichophyton mentagrophytes in agar medium10, unlike the aqueous extract from the dried leaf (1 mL/plate), which was also inactive against Epidermophyton floccosum, Microsporum canis and M. gypseum11.

The aqueous extract from the dried aerial parts (3.30 mL/L) showed stimulant activity in vitro in rat uterus12.

The aqueous extract from the fruit, the capsaicin and di-hydrocapsaicin showed antibacterial effects in vitro against Bacillus cereus, B. subtilis, Clostridium sporogenes, C. tetani and Streptococcus pyogenes in filter paper disk13.

The fresh fruit juice in vitro showed antibacterial activity against Escherichia coli andPseudomonas aeruginosa14.

The powdered fruit extract (50 g with 500 mL of ethanol 88%), in agar plate culture (50 µL/disk) did not show any activity against Staphylococcus aureus, Streptococcus pneumoniae orS. pyogenes15.

The fruit (5% in feed) fed to rat had an anti-hypercholesterolemic effect and is claimed to have gastric stimulating activity and choleretic effects16.

Solanine is claimed to have analgesic activity17; capsaicin is believed to be an analgesic, anti-inflammatory, a cyclooxygenase inhibitor, a local anesthetic, a rubefacient and a vasodilator17.

Capsaicin is also reported to cause local reduction of susbtance P, cyclooxygenase inhibition, anti-inflammatory, local anesthetic and vasodilating activities, among others18.
