Eating a diet high in fruits, vegetables, grains, legumes and plant-based beverages has long-term health benefits, [17] but there is no evidence that taking dietary supplements of non-nutrient phytochemicals extracted from plants similarly benefits health. [4]
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants.Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds.
Its seeds, leaves, bark, and flowers have been used medicinally for many centuries for treating joint pain, bladder and gastrointestinal problems, fever, leg cramps, and other conditions. It may be useful for treating chronic venous insufficiency. The raw plant materials are toxic unless processed. [7] Ageratina altissima: White snakeroot

Herbivores are animals that eat plants, carnivores are animals that eat other animals, and omnivores are animals that eat both plants and other animals. [24] Many herbivores rely on bacterial fermentation to create digestible nutrients from indigestible plant cellulose, while obligate carnivores must eat animal meats to obtain certain vitamins ...
Field biologists have provided corroborating evidence based on observation of diverse species, such as chickens, sheep, butterflies, and chimpanzees. The habit of changing diet has been shown to be a physical means of purging intestinal parasites. Sick animals tend to forage plants rich in secondary metabolites, such as tannins and alkaloids. [92]
Pharmacognosy is the study of crude drugs obtained from medicinal plants, animals, fungi, and other natural sources. [1] The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical , and biological properties of drugs, drug substances, or potential drugs or drug substances of natural origin ...
Spirulina is the dried biomass of cyanobacteria (blue-green algae) that can be consumed by humans and animals. The three species are Arthrospira platensis, A. fusiformis, and A. maxima. Cultivated worldwide, Arthrospira is used as a dietary supplement or whole food. [1] It is also used as a feed supplement in the aquaculture, aquarium, and ...
