Girón,278,CFEH

toothache:

  green fruit, mashed (or juice), applied locally 1-2

sapito (mouth candidiasis):

  green fruit and leaf, rubbed in mouth1-2

burning:

  leaf, mashed, cataplasm3

The ripe fruit of Lycopersicon esculentum is widely used for human consumption.

For candidiasis in the mouth and toothache:

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

For burns:

Wash injury with cooled boiled water and soap, apply 8-10 grams of leaf, previously washed, on the affected area.  Cover the injury with dressing or clean cloth and replace every 12 hours.

According to published and other information:

Use for candidiasis (thrush) in mouth, toothache and burns is classified as REC, based on the significant traditional use (OMS/WHO)4 documented in the TRAMIL surveys.

Traditional use should be limited only to superficial burns (skin injuries) that are not extensive (covering less than 10% of body surface) and are located away from high-risk areas such as face, hands, feet and genitals.

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

The leaf should be properly washed and cleaned, and its external indumentum (the covering of hairs on the leaf) should be removed, as it may cause dermatomucosal irritation and reactions of hypersensitivity.

TRAMIL Research25

The extract from the whole green fruit (100%) administered orally and intraperitoneally to mouse had in both cases an LD50 greater than 25 g/kg.

The hydroalcoholic extract (50%) of the entire dried plant, when administered intraperitoneally to mice, displayed an LD50 = 825 mg/kg26.

It has been reported that contact with the fresh leaf can cause dermatitis27.

The stem and leaf can be toxic due to their solanine content, which persists even after they have been cooked.  This alkaloid can cause signs of poisoning, such as loss of appetite, stomach pain, haematuria (blood in urine) and prostration (exhaustion)28.

The green fruit can induce a toxicity state similar to that of raw green potato, due to its glucoalkaloid content28.

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

The leaf has been widely studied and contains, among other components: phytoalexins5, steroidal alkaloids: tomatidine, soladulcidine6, lycoperosides7.

The fruit contains lignanes8; alkaloids: tomatine9, narcotine; biogenic amines: tryptamine and serotonine; organic acids: malic, citric and chlorogenic acids (with a much higher content in the green fruit than in the ripe fruit); volatile compounds:  acetaldehyde, benzaldehyde, acetone, ethanol, flavonoids and vitamin C10-13.

Proximate analysis of 100 g of green fruit14: calories: 24; water: 93%; proteins: 1.2%; fat: 0.2%; carbohydrates: 5.1%; fiber: 0.5%; ash: 0.5%; calcium: 13 mg; phosphorus: 27 mg; iron: 0.5 mg; sodium: 3 mg; potassium: 244 mg; carotene: 162 µg; thiamine: 0.06 mg; riboflavin: 0.04 mg; niacin: 0.5 mg; ascorbic acid: 20 mg.

Proximate analysis of 100 g of leaf14: calories: 40; water: 86.8%; proteins: 2.8%; fat: 0.6%; carbohydrates: 7.9%; fiber: 0.1%; ash: 1.9%; calcium: 433 mg; phosphorus: 86 mg; iron: 1.3 mg; thiamine: 0.08 mg; riboflavin: 0.47 mg; ascorbic acid: 175 mg.

The dried seed extract in vitro (32 µg/mL) inhibited protein synthesis15.

The ripe fruit showed no activity in vitro against bacteria that cause adverse skin conditions in humans16.

The aqueous extract from the fruit has been reported to have anti-mutagenic activity17.

The undiluted fruit juice was weakly active in vitro against Poliovirus I18.

The aqueous extract from the fresh leaf (1:1) in vitro showed antifungal activity againstFusarium oxysporum f. sp. lentis19, and against Ustilago maydis and U. nuda20.

The ethanolic extract (95%) from the aerial parts (50%) was active as a fungicide against Neurospora crassa, while the acetone and aqueous extracts were inactive21.

The dried stem was active in vitro as a fungicide against Sphacelia segetum22.

The ethanolic extract (95%) from the dried leaf (1%) applied externally was active as an antimicrobial agent (except against Herpes simplex), and can be used as a cosmetic for adults23.

The leaf has been reported to have insecticidal activity24.

Tomatine is claimed to have antifungal properties; in vitro it fully inhibited the growth of Candida albicans13.  When administered intravenously, it is described as a cardiotonic, antidiuretic, antihistaminic and anti-inflammatory agent, and it is believed to decrease cholesterol absorption13.
