Cinnamon
Cinnamon :
This herb has been used medicinally for thousands of years to fight tooth decay, clear up urinary tract infections and soothe stomach irritation. Chinese herbalists still recommend it for relieving nausea, fever, diarrhea, and menstrual problems. Modern herbalists disagree on its ability to aid in menstrual difficulties; some think it stimulates uterine contractions, while others believe it calms the muscle. Cinnamon oil is a different story. Applied to the skin, it may cause redness and burning. Taken internally, it can cause nausea, vomiting and possibly even kidney damage. Never ingest cinnamon oil. Culinary cinnamon is on the Food and Drug Administration's list of herbs generally regarded as safe. For healthy non-pregnant adults, there's no danger from medicinal doses
