Medicinal plants are herbs with one or some of their organs containing active ingredient. This substance, which forms less than 1% of the dry weight of the plant, has medicinal properties that affect living organisms. Medicinal plants contain parts of the plant that are sold after drying without any changes in shops and supermarkets. Herbal chemicals determine their therapeutic effect in terms of their function in the human body; therefore, herbs are classified according to their treatment radius in certain groups. A medicinal herb does not always have the same effect on disease, and its effects range may be high or low, which means that a plant may be effective in the treatment of several diseases; and vice versa, in order to strengthen their therapeutic effect, a mixture of several herbs is often produced to multiply their effects.
