The fruit and the juice of Citrus sinensis are widely used for human consumption and are an industrial source of essential oil.

For headache, flu and fever:

Prepare decoction or infusion with 5-20 grams of leaf in 1 liter (4 cups) of water. For decoction, boil for at least 10 minutes in a covered pot. For infusion, add boiling water to the 5-20 grams of leaf, cover pot and cool down. Drink 2-3 cups a day³⁶.

For conjunctivitis:

Instill (apply) in the eye 2-3 drops of fresh juice of fruit, 3 times a day.

For diarrhea, flu, cough, sprain, twist and fever:

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

According to available information:

Use for conjunctivitis, diarrhea, flu, cough, headache, sprains, strain and fever is classified as REC, based on the significant traditional use (OMS/WHO)⁴ documented in the TRAMIL surveys.

In any application to the eye, strict hygiene measures should be observed in order to avoid contamination or additional infection, and contact with any substance that may be irritating for the conjunctiva should be avoided. There exists the risk or increasing irritation with the application of Citrus spp juice.

For diarrhea, the use of this resource can be considered complementary to oral re-hydration therapy. Should there be a notable worsening of the patient’s condition, or should diarrhea last more than 3 days in adult or 2 days in children, seek medical attention.

Should there be a notable worsening of the patient’s condition, or should conjunctivitis or headache last more than 3 days, or should fever persist for more than 2 days, seek medical attention.

The essential oil of the plant can cause reactions of hypersensitivity.

La hoja fresca (liofilizada), vía oral (5000 mg/kg/día) a 10 ratones Hsd:ICR (CD-1) de 19.33 ± 1.99 g (5 machos y 5 hembras) durante 5 días con 15 días adicionales de observación, no presentó mortalidad, según el protocolo EPA.OPPTS 870.3100. El control se realizó con agua (0.4 mL/20 g de ratón) a otros 10 ratones de la misma cepa y características. Durante el ensayo ni en el periodo de observación posterior se presentó mortalidad, ni se evidenció ningún signo de toxicidad (Test Polidimensional de Irwing). No se observaron cambios en los pesos corporales más que los normales en la curva de crecimiento. La autopsia macroscópica no evidenció alteraciones en los órganos.

El jugo fresco puro del fruto, se administró en forma tópica (100 μL), en el saco conjuntival del ojo derecho, el ojo izquierdo control recibió 100 μL de agua destilada, en el modelo de irritación ocular, se observó por 72 horas sin revelar ninguna alteración ni irritación durante este período.

The fruit juice (29.5 mL/day) administered to rats inhibited the induction of colon cancer by azoxymethane³¹.

The fresh fruit juice (0.1 mL/plate) showed antimutagenic activity in vitro in the test for mutagenesis induced by sodium azide or 4-nitro-O-phenylenediamine in Salmonella typhimurium TA97 and TA100³².

The tincture of the green fruit peel (50 g of drug in 100 mL of ethanol 30%) demonstrated cytotoxic and genotoxic activity in vitro in Aspergillus nidulans (D30, FGSC, A593 y A594)^33-34.

The tincture of the green fruit peel (50 g of drug in 100 mL of ethanol 30%) administered orally to male and female rats (2 g/kg) did not show evident signs of acute toxicity, mortality or morphological or histological injuries in the organs studied (liver, heart, kidney, stomach, small intestine, large intestine and lung). The sub-chronic toxicity study (0.5, 1 and 2 g/kg/day) based on oral administration to male and female rats for 90 days indicated a decrease in body weight and in food intake, in the group treated with 1 and 2 g/kg, after the first month of treatment, and cycles of alternating irritability and depression in the group treated with 2 g/kg. Hemoglobin, hematocrit, differential leukogram, glycemia, TGO, TGP and alkaline phosphatase did not vary. No morphological or histological alterations were reported in the organs studied (liver, heart, kidney, stomach, small intestine, large intestine, lung, hypophysis, testicle and ovary). Oral administration to mice (0.5, 1 y 2 g/kg/day) in the bone marrow micronucleus did not report significant genotoxic activity, although a rising trend was observed in micronucleus PCE in association with the dose³⁴.

The essential oil in contact with the skin may cause hypersensitivity if the skin is exposed to the sun³⁵.

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

The leaf has been extensively studied and contains, among other components, alkaloids: caffeine⁴; terpenes: limonene⁵, b-amyrin; coumarins: herniarin, scopoletin⁶; flavonoids: rutin⁷, essential oils: linalool, sabinene⁸.

The fruit juice has been extensively studied and contains, among other components, vitamin C⁹; aliphatic compounds: ethyl butyrate, 3-methyl-butan-1-ol¹⁰; phenylpropanoids: caffeic, ferulic, p-coumaric¹¹ and chlorogenic acids; flavonoids: naringin, quercetin, naringenin¹², heptamethoxy flavone¹³, hesperidin, didymin¹⁴, neoeriocitrin¹⁵; carotenoids¹⁶.

The fruit extract (IC = 0.186 mg/mL) inhibited cyclooxygenase in vitro in the rat platelet model¹⁷.

The fresh juice of the fruit showed antioxidant activity in vitro against the free radicals of 2,2'-azino-bis-(3-ethylbenzothiazolin-6-) sulfonic acid¹⁸, as well as antiviral activity in vitro against Poliovirus I in cell culture¹⁹.

The aqueous extract from the dried pericarp (IC₅₀= 10.3 µg/mL) showed antibacterial activity in vitro against Salmonella typhi on an agar plate²⁰.

The fresh juice of the lyophilized fruit (5 g/kg) administered orally to Wistar rat on a hyperpurinic diet reported uricosuric activity, diminished the concentration of uric acid in the blood, by an increase of hepatorenal elimination, and induced urinary excretion, with no changes in diuresis. Urine acidity (pH) was not altered with regard to controls¹⁸.

The unripe fruit is claimed to have an anti-hyperglycemic effect, to induce glucagon synthesis and insulin secretion, and to have hypolipidemic effect. It is described as an hypocholesterolemic but not as an hypotriglyceridemic²⁵.

In a comparative study of the fruit juice of Citrus sinensis, Citrus paradisi and mineral water (350 mL/person) with itraconazole (100 mg single dose), administered orally to healthy adults, C. sinensis was found to reduce the mean life time of antifungal elimination by 56%, and the area below the curve by 41%²⁶.
