Lemon with garlicThe question has been brought up in my support calls over the years about some of the well-known detoxification foods, and their potential for side effects.  I thought I’d share some information about one of the most amazing foods on the planet: garlic.

Garlic is a useful adjunct to detoxification, because it conserves antioxidant levels, particularly glutathione, protects  against liver damage from acetaminophen, and can increase the intestinal activity levels of phase II detoxification enzymes. (In particular quinine reductase and glutathione transferase, used by the body to eliminate toxins).

Garlic protects your liver and heart from damage, and improves your ability to combat potentially fatal conditions like cancer and heart disease. Garlic may also help protect you from heavy-metal accumulation, smog and air pollution. It appears to be the sulfur compounds in garlic, especially allicin, that are most protective.  That little clove packs a powerful healing punch!

When it comes to detoxification, glutathione is one of the most important substances in the process.  It supports phase 2 liver detox, the more complicated of the two phases.  Because antioxidants get “used up” in the process of protecting you, exposure to toxic substances lowers glutathione levels.

Some background science: A study was conducted to see if garlic could be helpful in preserving glutathione levels by exposing a group of laboratory rats to a chemical known as bromobenzene. One group of rats was given garlic before being exposed, and their glutathione levels were tested both before and after exposing them to bromobenzene. When compared to a group of rats who were not pre-treated with garlic, the animals treated with garlic before exposure to bromobenzene had higher levels of glutathione after exposure than did the untreated group. More glutathione is a great thing!

Great, but what if you are among the small but significant group who has adverse effects to garlic? 

According to ConsumerLab.com, large doses of garlic can lead to upset stomach, facial flushing, rapid pulse, dizziness, allergies or insomnia, and can affect the mind and concentration.

Also, according to Chinese Medicine, garlic is  a warming and drying herb, so people with a hot constitution should use it cautiously, as it can create the side effects mentioned above.   People who have an angry temperament or reddish complexion would be classified as having a hot constitution and should proceed cautiously with garlic.

Not to worry, Nature has provided many great substitutes for garlic…

If you experience any of the above symptoms, you can still get the same benefits that garlic provides from other foods. As a substitute for garlic, scallions or spring onions can be just as effective as garlic, with less pungency.

Other foods and herbs also support phase 2 liver detox and can be used to support a successful detoxification program, including:

  • broccoli sprouts and other cruciferous vegetables
  • dill
  • caraway
  • turmeric
  • oranges and tangerines
  • dandelion
  • burdock root
  • apples
  • basil
  • jerusalem artichoke

So enjoy the benefits of garlic if you can and if not, know that there’s more than one way to detox a liver, and choose enjoyable foods and herbs that assist in the removal of toxins, leaving you light, strong and energetic.
