Benefits Of Basil

Updated: Aug 20


Basil, also known as its botanical name Ocimum basilicum is a flavorful, leafy green herb that originated in India (1). Basil is often used in cooking, herbal supplements, and herbal teas. There are many varieties of basil, but the most commonly used are holy basil, sweet basil, Thai basil, cinnamon basil, lettuce basil, and bush or Greek basil.


Benefits of Basil


Antibacterial Properties

An antibacterial property is when a substance, or in this case, an herb, can destroy or suppress the growth and reproduction of bacteria (2). In one study, they found the use of basil and rosemary in an essential oil form to potentially be an effective antibacterial agent as a treatment and prevention against emergent resistant strains in nosocomial infections (3).


Antifungal Properties

An antifungal property is when a substance, or in this case, an herb, can fight the growth of specific pathogens that could harm your health, such as ringworm, athlete's foot, tinea versicolor, toenail fungus, and jock itch (4). One study concluded that Ocimum basilicum L. essential oil had the potential to cure mycotic infections and act as a pharmaceutical preservative against Aspergillus flavus growth and aflatoxin B1 production (5).


Antimicrobial Properties

An antimicrobial property is when a substance, or in this case, an herb, can kill or suppress the spread of microorganisms such as bacteria, viruses, protozoans, and fungi (6). In one study, they found Ocimum basilicum and several other essential oils to have antimicrobial effects and anti-plaque effects as an alternative to oral supplementation (7).


May Improve Fasting Blood Sugar & Diabetes

Ocimum basilicum has been found to exhibit antidiabetic properties that are said to be due to its ability to suppress endogenous glucose release while also inhibiting glycogenolysis and stimulating glycogenesis (8). In one study, they concluded that basil aqueous extract had a positive response between rat intestinal sucrase and either rat intestinal maltase or porcine pancreatic α-amylase as a way to positively benefit diabetes (9).


May Reduce Hypertension

Hypertension, also known as high blood pressure, is blood pressure that is higher than average and puts you at a higher risk for heart disease, heart attack, and stroke (10). One study found that Ocimum basilicum has antihypertensive effects in renovascular hypertensive rats (11).


May Thin The Blood

Like aspirin, but natural without additives, Ocimum basilicum has been found to affect platelet aggregation induced by Adenine di-Phosphate (ADP) and thrombin resulting in an anti-thrombotic effect in vivo over seven days that disappear over 3-7 days (12).


May Protect Against Asprin's Damage To The Gut

Aspirin may help thin your blood, but it also causes damage to your gut like ulcers and is one of the most common hospitalizations for upper gastrointestinal (GI) bleeding (13). In one study, Ocimum basilicum was found to play a protective role against aspirin-induced gastric ulcers in mice (14).


May Reduce Damage From A Stroke

Basil has been found to reduce damage from a stroke while also supporting recovery from a stroke if given before or right after the stroke. One study found that Ocimum basilicum prevented ischemia and reperfusion in induced cerebral damage and motor dysfunction in the brain of mice when taken as a pre-treatment (15). Another study found that Ocimum basilicum improved memory and neurological deficit after ischemia-reperfusion as an after-care measure (16).


May Reduce Memory Loss & Increase Mental Alertness

Not only can basil improve memory after a stroke, but it can even improve memory loss associated with stress and aging. One study found Ocimum basilicum to improve chronic stress-induced neurodegenerative changes in mice (17). In another study, they found Ocimum basilicum to enhance the results of memory retention and retrieval in mice, which was said to be due to the antioxidant activity (18).


May Reduce Depression

Basil is also said to reduce depression related to chronic stress. In one study, they found Ocimum basilicum to relieve chronic unpredictable mild stress-induced depression in mice (19). In another study, they found Ocimum basilicum to have an antidepressant-like effect in animal models of depression (20).


May Prevent Certain Cancers

Basil has been found to prevent certain cancers, including breast cancer, colon cancer, and pancreatic cancer. One study found Ocimum basilicum essential oil, along with several others, to exhibit a degree of antiproliferative activity on specific cancer models, and basil was the most potent against human colon carcinoma (21). Another study found basil to have certain anti-cancer activities against diverse cancer cells (22). Another study found the sweet basil herb to contain a powerful component that may effectively increase human health and even prevent cancer (23).


Contraindications & Interactions

  • Some evidence suggests that basil extract can reduce systolic and diastolic blood pressure.

  • Theoretically, taking basil extract with antihypertensive drugs might increase the risk of hypotension.
