Allium sativum


Garlic that is used as a staple of modern cuisine is a domesticated version of the original garlic plant, which comes from ancient central Asia. Over the centuries, the plant flourished as a culinary and medicinal essential, being used to flavour meals and to treat ailments ranging from leprosy and parasites to haemorrhoids. It was also thought that hanging garlic bulbs on doors would check the spread of diseases such as smallpox. Modern science supports some of these remedies, although not its effectiveness as a deterrent against smallpox.

Garlic contains sulphur-containing compounds, one of which is alliin. When crushed or chewed, alliin becomes allicin, which is responsible for the distinctive aroma of garlic and has various health benefits.

Medicinal uses

Studies show that the compounds in garlic may be therapeutic in pain relief, worm removal, and in fighting bacterial, fungal and viral infections. It also appears to have anti-oxidant, anti-cancer, blood-glucose lowering, blood-pressure lowering and liver protection benefits. Further studies reveal that garlic may help lower cholesterol, prevent blood clots and spasms, act as an expectorant and alleviate swellings, sores and acne. It is recommended to:

  • Boost the immune system’s virus-killing T cells.
  • Lower cholesterol levels.
  • Possibly reduce blood pressure.
  • Help prevent heart disease.
  • Reduce blood clotting.
  • Fight infections such as colds and flu.
  • Help relieve symptoms of allergies.
  • Possibly help in preventing and fighting certain cancers.
  • Promote recovery from fungal infections such as athlete’s foot and the bacterium that causes stomach ulcers
  • Help protect the liver.
  • Lower blood glucose levels.


Talk to your medical practitioner before taking any herbal supplements.
In general, garlic has few side-effects apart from a garlicky breath. Occasional incidents of body odour or a burning sensation in the mouth and intestines have been reported. Garlic may interfere with some prescribed medicines. It can enhance the effect of medications used to prevent blood clots, but may increase the risk of bleeding in patients undergoing surgery.
