Herbalism (also herbal medicine or phytotherapy) is the study of botany and use of plants intended for medicinal purposes or for supplementing a diet.

Plants have been the basis for medical treatments through much of human history, and such traditional medicine is still widely practiced today.

Modern medicine recognizes herbalism as a form of alternative medicine, as the practice of herbalism is not strictly based on evidence gathered using the scientific method.

Modern medicine makes use of many plant-derived compounds as the basis for evidence-based pharmaceutical drugs.

Although phytotherapy may apply modern standards of effectiveness testing to herbs and medicines derived from natural sources, few high-quality clinical trials and standards for purity or dosage exist.

The scope of herbal medicine is sometimes extended to include fungal and bee products, as well as minerals, shells and certain animal parts.

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.

In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion.

The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes.

In chemical digestion, enzymes break down food into the small molecules the body can use.

A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts.

An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet; thus, the term vitamin is conditional upon the circumstances and the particular organism.

For example, ascorbic acid (one form of vitamin C) is a vitamin for humans, but not for most other animal organisms.

Supplementation is important for the treatment of certain health problems, but there is little evidence of nutritional benefit when used by otherwise healthy people.

A dietary supplement is intended to provide nutrients that may otherwise not be consumed in sufficient quantities.

Physiological or biological stress is an organism's response to a stressor such as an environmental condition.

Stress is the body's method of reacting to a .

Stimuli that alter an organism's environment are responded to by multiple systems in the body.

The autonomic nervous system and hypothalamic-pituitary-adrenal (HPA) axis are two major systems that respond to stress.

The sympathoadrenal medullary (SAM) axis may activate the fight or flight response through the sympathetic nervous system, which dedicates energy to more relevant bodily systems to acute adaption to stress, while the parasympathetic nervous system returns the body to homeostasis.

The second major physiological stress, the HPA axis regulates the release of cortisol, which influences many bodily functions such as metabolic, psychological and immunological functions.

The SAM and HPA axes are regulated by a wide variety of brain regions, including the limbic system, prefrontal cortex, amygdala, hypothalamus, and stria terminalis.

Through these mechanisms, stress can alter memory functions, reward, immune function, metabolism and susceptibility to diseases.

Definitions of stress differ; however, one system proposed by Elliot and Eisdorfer suggests five types of stress.

The five types of stress are labeled "acute time limited stressors", "brief naturalistic stressors", "stressful event sequence", "chronic stressors", and "distant stressors".
