Phytotherapy uses plant remedies in the treatment of disease. It is the oldest form of medicine known — practiced in many cultures for thousands of years, and even today, by 80% of the world’s population. Whole plants and plant parts are used throughout the world in herbal concoctions. Herbal remedies can be taken in the form of teas, capsules, tablets, extracts or tinctures, which are tailored to the individual, not just his or her symptoms. Herbal medicine’s effectiveness is due to the biological activity of its natural ingredients, chemicals and compounds. Many conditions can benefit from the use of herbal medicine, ranging from a simple common cold to chronic degenerative diseases.
