Diamond Laboratories Inc manufactures Kankunis slimming tea, which is marketed as a natural digestive aid to lose unwanted fat and relieve constipation, the manufacturer says. It contains three ingredients: senna, shiu sen tea and malvae. Although the tea may comprise natural ingredients, it is not without its risks and side effects.
Nausea and Vomiting
Senna is a stimulant laxative that can cause nausea and vomiting. This ingredient is present in several over-the-counter laxatives and may cause yellow-brown urine as well, according to Pub Med. The nausea and vomiting is due to the effect on intestinal mucosa in which the water and electrolyte secretion is altered, Drugs.com says. This may be too strong and cause discomfort and regurgitation of the tea.
Stomach Cramps and Diarrhea
The manufacturer says the ingredient senna is an Indian herb used as a laxative for many centuries. Although it does have a long-standing use as a digestive aid, the stimulant laxative is known to cause stomach cramps and diarrhea, according to Bill Church in his book "Medicinal Plants." Church says that although the mixture of shiu sen tea and senna may help to reduce the potential of irritation, you may want to add grated ginger to prevent cramping. Malvae, a combination of about 25 to 30 herbs and plants, stimulates and lubricates the intestines, which can cause diarrhea, Max Wichtl says in the book "Herbal Drugs and Phytopharmaceuticals."
If Kankunis tea is persistently used, the presence of senna may cause colon damage due to a laxative dependency. PubMed defines this as bowel movement difficulty in the absence of a laxative resulting in colon complications. Additionally, frequent diarrhea can also irritate the colon, cause dehydration and deplete minerals necessary for your health. The manufacturer warns that excessive use of the tea can cause an imbalance in electrolytes and fluid.
