Ocimum basilicum L. – Monograph


Order: Lamiales

Family: Lamiaceae


The genus Ocimum belongs to the family Lamiaceae, which includes most popular herbs/shrubs known for their medicinal properties and aroma profile. Due to the important morphological as well as chemical variability within the genus, its taxonomy and phylogenetic relationships are still debated. Moreover, the existence of chemotypes within single species increases the complexity to a higher level. [KumarA]

Occurrence of polyploidy and possibility of inter- and intra-specific hybridization within the genus lead to the occurrence of a large number of subspecies, varieties, and forms, which differ in essential oil composition and morphological characters. Over 120 species belonging to the Ocimum genus are currently recognized. [KumarA, WFO]

Basil, Ocimum basilicum L., is probably native to the tropical regions of Africa and Southeast Asia. The generic epithet Ocimum comes from the Greek ὤκῐμον (ócimon), which in turn derives from ὄζω (ózo), that means ‘to smell, to give off an odor’ due to the characteristic scent of the plants. Both the common name ‘basil’ and the specific epitheth ‘basilicum’ come, instead, from the greek βασιλικόν, that means “regal”.

Known to most people as a spice and used in cuisines across the world, from Thai to Italian, it is probably one of the most frequently used kitchen herbs, sitting in sunny kitchen windowsills across many lands and in many times, as Fuchs records in 16th century Germany and Bauhin in the 17th regarding the reports of scorpions commonly making their homes under pots in Venice. [Tobyn]

Yet the chances to find it in any modern herbal are very low. Maud Grieve’s A Modern Herbal (1931) has an entry for basil with some information (the plant name etymology, the plant history and the description of some varieties) but no real indications or uses2.

According to Mrs. Grieve, “the physicians of old were quite unable to agree as to its medicinal value, some declaring that it was a poison, and others a precious simple.” [Grieve] Indeed, most ancient and even more modern authors do not agree about the real virtues or defects of this aromatic herb.

Culpeper writes that “it carry a kind of virulent quality with it” and reports the controversial opinions the classical authorities had about this herb: “Galen and Dioscorides hold it not fitting to be taken inwardly; and Chrysippus rails at it with downright Billingsgate rhetoric; Pliny, and the Arabian physicians, defend it” [Culpeper]. The author ends the paragraph with a concise and clear “I dare write no more of it.

Pliny relates Chrysippus’ superstitions concerning basil: that the bruised herb placed under a stone will breed a serpent; or that the herb chewed and put in the sun will breed worms and maggots; that basil pounded with crabs or crayfish will attract all the scorpions of the area to gather around the bait; or finally, that if you are stung by a scorpion on a day when you have eaten basil, you will surely die. Anyhow Pliny has also made it clear that basil possesses medicinal qualities, including that of treating scorpion stings, when applied externally with wine and vinegar. [Tobyn]

Ibn Sina reckons the internal consumption of basil generates turbid and melancholic blood from its superfluous humidity. [Tobyn]

According to Dioscorides, “Eaten much in food it dulls the eyesight. […] Some abstain from eating it in food, because when it is chewed and set in the Sun it breeds little worms.” (see [Durante, Mattioli]).3

The story of basil goes on this way until the Age of Enlightenment, causing disagreement among most authors. Therefore, it is it no surprise that basil would have easily disappeared from the herbal pharmacopoeia. [Tobyn]

Speaking of the qualities of basil, Castore Durante writes: “It is hot in the second degree, & has a superfluous dampness in itself, & yet it is not so fit in foods, as it is very conveniently administered externally both to ripen, & to digest; it has the faculty to open, expel, & provoke; it is enemy to the stomach, for being very hard to digest.” [Durante]

According to Pelikan: “This plant […] was used in medicine for its digestive organs warming, uterus purifying, childbirth facilitating, milk secretion promoting, aphrodisiac action. Its effectiveness is also in catarrhal diseases and inflammation of the mucous membranes of the urogenital system. As in other Labiates, there is also a calming, spasmolytic action.” [Pelikan]

According to Matthew Wood, “sweet basil removes heat and toxins from the bloodstream, liver, portal circulation, and intestines. [… It] opens the skin and lungs, relax the digestive tract, and purge the blood of heat and toxins. It detoxifies through the skin by diaphoresis and removes mucus from the lungs […]. It stimulates the appetite and digestion, removing stagnant food and flatulence. It also penetrates to the deeper regions of the organism to detoxify the blood, liver, portal circulation, spleen, and intestines.” [Wood]

The same author also reports the following quote: “Basil appears to dissolve and liberate for excretion, toxic lipophilic compounds which are stored in body fat deposits. It especially neutralizes past (and long past) damage to the body from recreational marijuana use”. [Wood]

As a gynaecological remedy, basil is a gentle cleanser and strengthener of the womb, and may have a role in both facilitating conception and in managing labour. It may encourage breast milk in the nursing mother. [Tobyn]

Nervine effects of sweet basil are quite complex. Various authors define it as a sympathomimetic drug [Valnet], a parasympatholithic drug [Paoluzzi], both sympatholithic and parasympatholithic [Duraffourd-Lapraz], or more simply a drug that acts on both the sympathetic and the parasympathetic sides of the autonomic nervous system [Wood]. Indeed, basil first stimulates, then relaxes the brain and nervous system, and it is used both for insomnia and to enhance alertness [Wood]. This makes sweet basil a really interesting drug, capable of rebalancing the ANS.

Sweet basil may have a place in chronic fatigue syndrome and similar deficiency states, especially where gastrointestinal symptoms or a depressed mood are evident, or where chronic pain is experienced. [Tobyn]

Prolonged use of the essential oil during the day stimulates concentration and frees the head from thoughts, “separates Pure from Impure” and acts on the Heart (in the sense of Shen). It has a strong influence on emotions and can be of great help to those suffering from fear and sadness. [Paoluzzi]

According to Jean-Claude Leunis, basil “is the plant of dystonia in the nervous patient, still dynamic, but nervously exhausted. These patients often have an increase in albumin accompanied by a hypoglobulinic profile. It also stimulates the cerebral cortex and is indicated in memory loss and dynamism. It acts by stimulation of the adrenal glands. Its tropism is intestinal and can be used alone in the treatment of pseudomembranous colitis.” [Leunis]

O. basilicum (Jiu Cheng Ta – 九層塔) is also used in Traditional Chinese Medicine (TCM) as a “herb that Regulate Qi”. It is classified as an acrid, warm herb that enters the Stomach, Liver and Kidney meridians.

It’s used to:

  • Regulate the Middle Jiao and promote digestion, in case of Stomach Cold with Qi Stagnation with stomach cramps which are better with warmth and worse with pressure and poor appetite in children.
  • Invigorate Blood and dispel water, in case of obstetric and gynecological disorders from Qi and Blood Stagnation with irregular menstruation; postpartum Blood Stagnation.
  • Open the channels and collaterals and relieve pain, in case of soreness and pain in the tendons and bones.
  • Eliminate toxins and disperse Wind, in case of toothache and eye swelling and pain (when combined with Heat-clearing and toxin eliminating herbs). [AmDragon]


Sweet basil and scorpions

Sifting through the myths and superstitions reported about basil, it is interesting to note that one often encounters the motif of scorpions, either in a positive or negative sense: indeed, some authors repute this herb able to cure the bite of a scorpion or to render it harmless, while other authors tell it increases the danger up to the point that anyone who is stung by a scorpion on the same day he ate basil will surely die.

In addition to what Pliny reports about Chrysippus (see above), Dioscorides recommends basil for bites of the sea dragon and for scorpion stings. He relates how Arabs eat the herb to remain without pain if they get stung: “The Arabs said that, being pierced by Scorpions, those who ate Basil that day feel no pain.” [Mattioli, Tobyn]

According to Mattioli, “Galen mentioned it in the second [book] of the faculties of food, saying: There are many who use Basil in food, as if little is commended. Lie those who say that placing it chopped in a well covered earthen jar, and especially placed in the sun, generates Scorpions; because this is completely alien to the truth.” [Mattioli]

The same author also reports that “drunk with wine, and with a little vinegar it heals the stings of marine and terrestrial scorpions, no less than the rue and mint.” [Mattioli]

Castore Durante (referring to the basil called ‘gentle’4) writes: “The present age cheerfully defends Basil against the opinion of the ancients by saying that goats eat it, and drunk it with wine, and with a little vinegar, it heals the stings of the marine, & terrestrial scorpions, no less than the rue, & the mint. If anyone is hurt by the scorpion, in the same day he has eaten basil, he will hardly heal, frequently eaten in foods it generates lice.” [During]

Culpeper reports that “Hilarius, a French physician, affirms upon his own knowledge, that an acquaintance of his, by common smelling to it, had a scorpion bred in his brain.” [Culpeper]

Still Culpeper makes it a herb of Mars in Scorpio, projecting the association of the plant with scorpions onto the astrological plane.



Temperature and taste

The plant is classically classified as hot in the second degree and as having a “superfluous dampness” which makes it poorly suitable for digestion [Durante, Gerard, Mattioli].

Castore Durante says about ‘gentle’ basil that “the more it is perfumed, the hotter it is than the other” [Durante]. Clearly this is also true for any variety of basil: the more aromatic and spicy it is (depending on the concentration and composition of the essential oil, which may also contain eugenol, methyleugenol and camphor) the hotter it is.

Flavor is certainly dependent on the specific variety. In general we can classify it as: aromatic, pungent, bland (due to mucilages), slightly salty.



According to Culpeper, sweet basil is a “herb of Mars, and under the scorpion.” [Culpeper]


Tissue phases



Actions and indications

Humoral actions

Being aromatic and pungent it is a warming, digestive, resolving, astersive, diffusive and tonic plant that eliminates excesses and stasis of Heat, Phlegm, Phlegm-Heat and Tension, but is also able to supplement Tension (especially in the Kidneys, Heart, Stomach and Liver). It moves the body fluids, “opens the pores” and resolves the “oppilations” (this is especially true for the spicier varieties).

The presence of mucilages and the slight saltiness make basil humectant and emollient and therefore capable of providing correct Phlegm, but they also make it able to prepare thickened and adust Phlegm and Melancholy for elimination.

According to the Ayurvedic medicine, it treats kapha and vata excesses.



Sweet basil tropism is complex. It mainly acts on kidneys and adrenals, heart, stomach and digestive system, lungs, spleen liver, skin and the autonomous nervous system.

Used parts and collection

The whole basil plant can be used: leaves, aerial parts before flowering, flowering tops, roots and seeds. The mature flower head contains the most complete representation of the properties [Wood].


Preparation and dosage

Basil can be used fresh or dried or a tincture can be made with it. Some varieties lose their aroma when they are dried (for example, Genovese basil and the varieties derived from it) and therefore it is preferable to use them fresh.

The recommended dosages for the herb and the tincture also vary significantly between the various authors.

According to Duke: 1–2 tsp herb/cup water 2–3 ×/day; 0.5–1 tsp tincture up to 3 ×/day; 5g leaf/200 cc water for gas; 20 g leaf/300 cc water for aphthae; 15 g fresh plant/l water, one cup before retiring. [Duke]

According to Menzies-Trull, a physiomedicalist, the dried herb can be given in doses of 3 g, or as 30 ml of the infusion or 4 ml of the tincture. [Tobyn]

In traditional Chinese Medicine usually 5-12g of dried herb are employed. [AmDragon]


Contraindications and side effects

Sweet basil can be considered a safe plant (LD50 hydromethanolic extract >= 2000 mg/kg; LD50 powdered herb >6000 mg/kg). [Duke]

The herb and essential oil should not be used during pregnancy and lactation (use as a condiment may be regarded as safe). [AmDragon, Duke, Tobyn]

Use caution with the essential oil of basil and do not use it over a long period. [Duke, Tobyn]

The essential oil is slightly hypnotic in high doses. [Mailhebiau]

Sweet basil extracts can inhibit phase I (e.g. CYP2B6) and increase phase II hepatic enzymes. [Dasgupta, KumarS]



Ocimum basilicum has practically not been studied in homeopathy. Only Jan Scholten has published a sense proving [Scholten] and a dream proving [Scholten2]. The information below is taken from [Scholten]11.

People needing Ocimum basilicum keep going in a hopeless situation seeking acknowledgment. They have a compassionate, social nature, serving others in order to be recognised, but they have problems making changes and evolving because they are fundamentally conservative and traditional. Values are important. They are devoted, self-sacrificing and of high moral feeling. They are more down to earth that for example Aristolochiaceae and ambitious in a simple way. They are simple but have a royal aura.



Devoted. Self-sacrificing.


Need a devoted atmosphere.

Religious but down to earth.




Does not understand what happens to him.

Despair, < loss of relative, < not being understood.


On the wrong track.

Wants to be recognised as part of the group.

Delusion: not being appreciated; being downtrodden in a mud city, being the doormat of her parents.

Dreams: teeth falling out; walking in a churchyard, in meadows with flowers and cows, swollen abdomen, itch under feet, making love, doubting to let her breast be operated on, enlarged, fitting her night gown, meditating.



Desire: refined food.



Nose: obstructed.

Throat: raw, burning.

Urinary: cystitis; difficult urination.

1. See Notes on humors.

2. In fact, Grieve’s herbal has an entry for bush basil (also known as Greek basil), O. minimum, and describes some uses of this plant that shares several properties with O. basilicum. Indeed, also classical Italian authors such Castore Durante and Pietro Andrea Mattioli mix somewhat the properties of both Ocimum species.

3. This is also reported from a modern Chinese author, Lu Zhao, which writes, in his “Ethnopharmacological Study of Aromatic Uyghur Medicinal Plants In Xinjiang, China”, that basil is “harmful to eye, can reduce vision”, also suggesting a couple of possible remedies: “grape vinegar or purslane.” [Zhao]

4. Probably Ocimum minimum L.

5. Mattioli reports that even specifically the ‘gentle’ basil “is given to smell with vinegar in syncopes, and other defects of the heart” [Mattioli]. So this is valid both for basil in general, as Pliny suggests, and for ‘gentle’ basil.

6. Ayurvedic term for skin disease.

7. This symptom is produced, according to the classical authors, only in case of excessive food consumption.

8. According to the authors, O. basilicum may act in a manner similar to that of telmisartan, which is an antagonist of the receptors to angiotensin type 1.

9. Sweet basil is a hypoglycemic drug, but Matthew Wood suggests it for hypoglycemia too. [Wood]

10. Even if, according to some classical authors, “eaten at table with vinegar, the herb strengthens the female womb and can be used to repress breast milk when it is time to wean the child.” (see [Tobyn]). John Gerard writes that basil is galattofuge: “Dioscorides saith that if Basill be much eaten, it dulleth the sight, it mollifieth the belly, breedeth winde, prouoketh vrine, drieth vp milke, and is of a hard digestion.” [Gerard]. But it is a bad translation from Dioscorides, since the latter tells exactly the opposite, that is “increases the milk” (see [Mattioli]).

11. Which also includes data from [Scholten2].

12. Bon-vivant.
