Gingili (Seasame) is one of the great oil seeds of the world. Gingili probably originated in Africa and was cultivated in India before it reached the Mediterranean. In the first century gingili oil was exported from India to Arabia and Africa and thence to the Roman Empire. The rich , almost odourless oil expressed from the tiny seeds which may be black, red or yellow is very stable. Gingili oil contains an antioxidant system comprising sesomolinol formed from sesomolin which substantially reduced its oxidation rate. If properly stored, gingili oil is not likely to go rancid, making it popular as a cooking oil in India, China and Sri Lanka. It is also highly nutritious, rich in Vitamin A , B, and E as well as minerals iron , calcium, magnesium , copper, silicic acid and phosphorus. It contains linoleic acid and alph-linoloic acid as well as lecithin and this explains why it is beneficial to the brain and nervous system.

Like olive oil, gingili oil is considered good for lowering LDL (the harmful) cholesterol level. The gingili seeds contain 44 to 57% fat which has carotene and high iodine number, lioleic acid content being about 45% and F/S ratio greater than 4.

In ancient Mesopotamia as in modern India, it was used in anointing the body. Cleopatra is said to have used gingili oil as a skin oil - Gingili oil is used for culinary purposes, in soap manufacture and as lamp oil.

The seed also contain 20 to 25g protein, 1200mg calcium and 9mg iron per 100g and is a good supplement for rice diet. The protein is rich in tryptophan and methionine and has same nutritive value as ground nut protein. The press-cake has 40 - 48 % protein and has been used in Central America in correcting under nutrition in children. In Sri Lanka the press- cake is converted into cattle feed.

Gingili seeds roasted gently in a dry pan could be added to salads, vegetable dishes casseroles, meat loaves and stuffing. A paste can be made from the seeds as a substitute for butter.

Gingili oil is immensely popular in India where its use in oil massage (Abhayanga) is part of every day life and an important aspect of Ayurveda. It is the favourite oil for massage as its chemical structure gives it a unique ability to penetrate the skin easily nourishing and detoxifying even the deepest tissue layer. It is the best oil for balancing ‘Vata" and can be used sparingly for "Pitta" and "Kaphe". Used regularly, gingili oil is wonderful for reducing stress and tension, nourishing the nervous disorders, relieving fatigue and insomnia and promoting strength and vitality. Those persons who use gingili oil have reported feeling stronger and resilient to stress with increased energy and is useful for muscle spasm, sciatic pain, dysmenorrhoea, colic, backache and joint pain.

The antioxidant explains gingili oil’s reputation for slowing the aging process and increasing longevity and certainly regular oiling of the skin restores moisture to skin, keeping it soft, flexible and young looking. It also lubricates the body internally particularly the joints and bowels and relievers irritating cough, cracking joints and hard stools.

Research into the healing effect of gingili oil is beginning to emerge. A recent research study undertaken to investigate the effect of gingili oil in treating hypertension patients by Dr. D. Sankar et al in Department of Biotechnology, Vinaya Mission Foundation University of Chennai, India shows that gingili oil lowers blood pressure in high blood pressure patients and patients who consumed gingili oil daily could omit or reduce the dose of hydrochlorothiazide (HCT) and atenolol in case of mild and moderate hypertension. A significant reduction of systolic and diastolic blood pressure and body mass index (BMI) had come down when gingili is consumed. Gingili oil could decrease lipid peroxidase and increase the antioxidant status of hypertensive patients.

It is a good idea if our physicians who are interested in hypertension do a research study using gingili oil for mild and moderate hypertension. Gingili oil is quite popular among people living in the northern part of Sri Lanka. As mentioned earlier good, pure gingili oil does not smell. It is noteworthy that ‘some of the so- called "Pure gingili oil " sold in boutiques and supermarkets and some of the Ayurvedic drug stores in Colombo are adulterated gingili oil.
