Herbs have been used for thousands of years in many different cultures to treat illness. The word herb simply refers to a plant or a part of a plant that is used for medicinal purposes, or as a spice or fragrance.
Herbal medicines generally work the same as conventional medications—they contain chemical ingredients that have an effect on our bodies when we take them.
You may use herbal remedies to treat minor symptoms instead of an over-the-counter medication. They are commonly used to treat ailments like stomach discomfort, cold, flu, headache, menstrual pain, insomnia, minor aches and pains, and digestive problems such as diarrhea or constipation. There are also herbal remedies believed to relieve depression, anxiety, PMS or stress.
