Super Dieter's Tea is a tea product containing senna and generally consumed by those wishing either to relieve occasional constipation or to cleanse. According to the manufacturer, Super Dieter's Tea may help support weight loss efforts. It contains roughly 10 ingredients including the sweetener stevia, but its cleansing properties are due to the herb senna which functions as a mild laxative and can cause or worsen diarrhea, loose stools and abdominal pain, according to the National Library of Medicine.
Diarrhea may result from consuming Super Dieter's Tea. Senna decreases the time it takes for food to travel through the digestive tract, causing frequent stools, and as a result, the colon may not adequately reabsorb water, causing loose stools. Diarrhea is defined as an increased frequency of stools, greater than three per day, or a decreased consistency of stools, caused by excess water, compared to what is normal for you.
Abdominal pain, often in the form of cramping, is another possible side effect of Super Dieter's Tea. Senna increases the speed of digestion by stimulating rhythmic contractions of the colon, and cramping can result, and it may be accompanied by nausea, which should not lead to vomiting. Stop using the product if symptoms are severe or do not go away, and if symptoms persist after discontinuation, see your doctor.
In addition, senna may cause your urine to turn yellow-brown, but this condition is harmless, according to the National Institutes of Health. It is very uncommonly associated with more serious symptoms such as bloody stools, dizziness and weakness, which may be due to water loss in the form of diarrhea. Talk to your doctor if these symptoms occur.
