HEALTH BENEFITS OF BASIL LEAVES AND OILS
Basil (Ocimum basilicum L.) originates in the Mediterranean Sea and
Middle East. [1] It is a popular culinary herb, and its essential oils
have been used extensively for many years in food products,
perfumery, and dental and oral products. [14]
What are the health benefits of basil leaves and oils?
BASIL ESSENTIAL OILS MAY HAVE BENEFITS OF ANTI-ULCER, ANTI-
MICROBAL ACTIVITIES.
The fixed oil of Ocimum sanctum L. (Labiatae) was found to possess
significant antiulcer activity against aspirin-, indomethacin-, alcohol-,
histamine-, reserpine-, serotonin- and stress-induced ulceration in
experimental animal models. Significant inhibition was also observed
in gastric secretion and aspirin-induced gastric ulceration in pylorus
ligated rats. O. sanctum fixed oil may be considered to be a drug of
natural origin which possesses both anti-inflammatory and antiulcer
activity. [17]
Basil essential oils and their principal constituents were found to
exhibit antimicrobial activity against a wide range of Gram-negative
and Gram-positive bacteria, yeast, fungi and mold. [9,14-16] It may
also help relieve intestinal gas. [10] The major active ingredients of
basil essential oil are terpenoids, such as eugenol, thymol and
estragole. These ingredients contribute the potential health benefits
of basil.
BASIL SEED MAY HELP CONSIPITATION
Its seeds are thought to benefit people with constipation or diarrhea.
Researchers believe that its seed may prevent sugar absorption by
providing dietary fiber and relive constipation by acting as a bulk-
forming laxative. [7-8]
BASIL LEAF EXTRACT MAY HAVE ANTI-CANCER EFFECTS
Basil leaf extract was very effective in elevating antioxidant enzyme
response by increasing significantly the hepatic glutathione
reductase, superoxide dismutase, and catalase activities. . Chemo-
preventive response was evident from the reduced tumor burden (the
average number of papillomas/mouse), as well as from the reduced
percentage of tumor bearing-animals. [13]
Experimental studies on albino rats reported that leaf extract of
Ocimum sanctum and Ocimum album (holy basil) had hypoglycemic
effect. While human study also showed a significant decrease in
fasting and postprandial blood glucose levels during treatment with
holy basil leaves compared to during treatment with placebo leaves.
Thus, basil may benefit people suffered from type 2 diabetes. [4-6, 18]
SWEET BASIL MAY HAVE BENEFITS OF ANTI-THROMBOTIC
EFFECTS
In a study of rats, oral administration of aqueous extracts of Ocimum
basilicum L inhibited platelet aggregation induced by thrombin and
ADP in a dose-dependent fashion. [11]
ITS RELATIVE MAY HAVE BENEFITS OF ANTI-EPILEPSY EFFECTS
Researchers from India noted that solvents extracts of holy basil
(Ocimum sanctum Linn) were effective in preventing tonic convulsions
induced by transcorneal electroshock. [12]
BASIL SIDE EFFECTS
One of its ingredient, estragole, is believed to be carcinogenic. [12]
However, it may not be a concern to use basil as a seasoning in food.
