Medicinal Plants: Introduction to Botany
Botany is a branch of biology studying plant life, including: structure, growth, taxonomy, systematics, reproduction, metabolism, physiology, biochemistry, development, diseases, ecology, and evolution of plants.
- Bryophytes: nonvascular plants that include liverworts, hornworts, and mosses
- Tracheophytes: seedless vascular plants that include clubmosses, trimerophytes, ferns and horsetails
- Spermatophytes: seed vascular plants that include conifers, cycads, ginkgo, gnetae, and flowering plants

Phytotherapy is the use of plants or plant extracts for medicinal purposes (especially plants that are not part of the normal diet).
The carotenoids in primrose produce bright red, yellow and orange shades. People consuming diets rich in carotenoids from natural foods, such as fruits and vegetables, are healthier and have lower mortality from a number of chronic illnesses.
Pharmacognosy is the study of all medicines that are derived from natural sources.
The bark of willow trees contains large amounts of salicylic acid, which is the active metabolite of aspirin. Willow bark has been used for millennia as an effective pain reliever and fever reducer.
Phytochemistry is the study of phytochemicals produced in plants:
- Amino acids & derivatives
