Adverse Effect of Essiac Tea & Drugs

Essiac is an herbal blend typically used to prevent and fight illness. The traditional essiac recipe consists of burdock root, slippery elm bark, sheep sorrel and Turkish or Indian rhubarb, but some manufacturers add blessed thistle, kelp, red clover and watercress. Originally developed as a cancer treatment by a Canadian nurse in the 1920s, essiac is renowned for its immune-boosting and detoxifying properties and is available in many forms, including supplements, liquid extracts and tea. But essiac isn't for everyone; some users experience side effects from this herbal formula.

Diarrhea

• Diarrhea and gastronomical discomfort are common side effects of essiac, especially when it is first consumed. Users experiencing diarrhea are advised to reduce their dosage to 1 oz. per day until the problem is resolved.

Allergic Reactions

• The common essiac ingredient sheep sorrel is a known allergen. Users experiencing itchy rashes, runny eyes and fevers should discontinue essiac immediately.

Kidney Stones and Problems

• Users with a history of kidney stones and ailments should avoid essiac blends containing sheep sorrel and Turkish rhubarb. Both ingredients contain oxalic acid, which is known to cause kidney stones to form.

Lower or Higher Blood Sugar

• Because burdock root, a common ingredient in essiac blends, can sometimes affect the body's glucose levels, persons with diabetes should first consult their doctor before using essiac.

Warning

• Pregnant or lactating women are advised not to take essiac because ingredients containing oxalic acid can have a negative effect on the baby's development. Also, ingredients such as Turkish rhubarb and burdock can cause the uterus to contract, and some studies have shown that whole slippery elm bark carries a higher risk of miscarriage.
