Natural-product is produced either by developing a new drug, using extracts from natural products that are known for their treatment effects based on the long-term experiences and practices of traditional medicine, or by developing a drug using prescriptions of traditional medicine that are data based.
Most new natural-product developments have been based on using phytochemicals (plant-based chemicals, plant chemistry) in order to extract substances only for pigments, food additives, spices, perfumes, or air-fresheners. However, newly-developing movements for natural-product drugs are beginning to focus on the substances, such as flavonoids, contained abundantly in apples, grapes or tangerines, capsaicin, one component of peppers and black peppers, and saponins, contained in ginsengs, soybeans, garlic, onions, and a variety of bean family plants.
