Allium sativum (Lahsun, Garlic)

A nutritionally balanced diet is key to good health. Everyone should try to understand the importance of a balanced diet and natural home remedies to enjoy a healthy life. One benefit of natural home remedies is that they have negligible side effects. People who maintain a balanced diet generally do not require medicines, as mentioned in the ancient Ayurvedic text, Kashyap Samhita.

Let us discuss the medicinal value of Allium sativum and its uses in food recipes.

The Sanskrit name for Lahsun (Garlic) is ‘Rason’ because it contains five Rasa (tastes) except Amla (sour). Garlic has been used for medicinal purposes and cooking since ancient times.

The active constituent of Allium sativum is Allicin, which has hypolipidemic action. It inhibits cholesterol biosynthesis in the liver. Allicin is produced when garlic is crushed for medicinal value or culinary purposes, so it should be used after crushing it when preparing food.

Benefits of the Contents of Garlic

- Allicin: Contains sulfur, which helps prevent infections, kills bacteria and has antifungal properties.

- Salicylate: Acts as a blood thinner.

- Selenium: Known to fight cancer.

Action of Garlic in Body Systems

- External Use: Poultice is used in sciatica, paralysis, swelling, and backache to relieve pain.

- Digestive System: Indicated for loss of appetite, indigestion, colic, worms, and piles.

- Circulatory System: As a stimulant, it can be used to treat heart problems.

- Respiratory System: Useful in treating chronic cough and asthma.

- Reproductive System: Used for dysmenorrhea.

- Urinary System: For intermittent urination.

Medicinal Uses

Garlic has medicinal uses as a carminative, antibacterial, anti-inflammatory, stimulant, anthelmintic, and antirheumatic. It acts as an anthelmintic, expelling roundworms. The oil of the seeds is also a stimulant. Allium sativum is a natural cleansing and disinfecting medium. Its extract shows activity against Gram-positive and Gram-negative bacteria due to its allicin content.  

Ref: Wealth of India Rev Vol 1, 1985, CSIR, 184-185.

Results of a study by Sevendsen L. et al., Laboratory of Cellular Ageing, Aarhus University, Denmark, show that garlic extract has youth-preservative and anti-aging effects on humans.

Clinical Trial

In my practice, I observed that Lashunadi Bati, given one Bati twice a day to 10 patients for about 15 days, exhibited significant results for patients with gas, belching, indigestion, and nausea.
