Example Input: THis product (which i am not allowed to return) has ingrediants of salt, spices, hydrolysed soy protein, that last item is the common industry con for adding msg to your food. Every soup on your grocers shelf contains msg, but, i digress. So, the third ingrediant is a form of MSG, further down the ingrediant list is proudly displayed ... Monosodium Gludamate, ...MSG. This does not add spice to your food, it stimulats your tongue into feeling that the food tastes good, when IT DOES NOT. MSG can make dogfood taste like hamburger. anyone who thinks this is making their food taste cajun may be serving ALPO. Tones and Durkee (sp) do not contain MSG, I prefer Tones! I have 8 eight ounce cans of this stuff.. would anybody like to buy some hamburger from me?

Example Input: Oh my gosh. I bought this tea and drank my first cup in the late afternoon. By evening I was having the worst stomach cramps and diarrhea. I belatedly looked at the ingredients and the first one is senna leaves. During internet research I discovered that some individuals may experience discomfort or cramping after using senna products. Also the following admonition - don't take senna for more than a week or so or your body could end up relying on it to contract your bowels. Side effects can include: *diarrhea *intestinal cramps or gripping pains *rash *severe weight loss Senna should not be used by persons with Crone's disease, Diverticular disease and other similar diseases. Senna is not a daily or causal supplement and excessive use can cause liver damage. I wanted to die my insides hurt so bad. Any weight loss you may accomplish with this tea may not be worth the pain. Be aware before you use. I threw my remaining 29 tea bags away!
