Most modern herbal medicines have been chemically manufactured but the herb is the most important and healthy for the plant in the two types of active substances for treatment and another substance that destroys toxic negative products from the metabolism of the medicine in the liver to make it easier to excretion
Herbal medications are helpful in the sense they do not have some of the side reactions associated with chemical drugs. On the other hand if you are looking for quick results herbal medication will take a longer time because it is based on discipline and making them a way of your life. If I have a headache I will rather depend on 2 pills of 325 mg aspirin than resort to an herbal routine. Herbal medications require that you take them for a long duration and are disciplined in other lifestyle issues as well.
