Herbalism refers to the study or use of parts of plants for example roots and leaves as medicine to treat illnesses. Throughout history, people have relied on herbs for wellness. Some research on herbs used to treat specific diseases had been done and documented.
Herbs have been used since ancient times. We find that the Chinese have collected and written information on how herbs work on different people for the past 2000 years (Leung, 2006). Back in the day, Africans and Native Americans used herbs for healing rituals and cosmetic purposes. This knowledge of healing with herbs has since been passed down to their children and grandchildren.
Pharmaceutical drugs originated from herbs. When chemical analysis became available to scientists, they started extracting some parts of plants to make pharmaceutical drugs.
The use of plants to treat ailments is increasingly becoming more popular. The World Health Organisation has estimated that approximately 80% of people are relying on herbal medicine in the early stages of illnesses (WHO, 2005). The reason people have been opting for herbs is that they are not happy with the high prices of pharmaceutical drugs for example in the United States. People also believe that herbs are better than manufactured forms of medicine (Bandaranayake, 2006). Herbalism is now becoming more popular also because of improvements in clinical research and quality control.
The way herbs work is not yet completely understood. This is because scientists do not know of the specific components that treat particular illnesses. Herbs contain many components which combine to help treat different illnesses. The environment in which herbs grow also determines their effectiveness.
Herbs help when used appropriately. However, it is important to take note that some herbs are inappropriate for people with certain medical conditions. Some cannot be used at the same time with certain pharmaceutical drugs.
