Since toxic or bad tasting secondary compounds have an obvious benefit for the plant, it is hardly surprising that most secondary compounds have neutral or harmful effects for animals however, through trial and error, humans and some other species have discovered that under the certain circumstances, the physiological effects of some secondary.

The release of secondary compounds by one plant that have an effect on neighboring plants is referred to as allelopathy if a plant can reduce the growth of nearby plants by releasing chemicals into the soil, it may increase its access to light, water, and nutrients and thus its evolutionary fitness. Secondary metabolites are organic compounds produced by plants which are not directly involved in the normal growth, development, or reproduction of the organism unlike primary metabolites , absence of secondary metabolites does not result in immediate death, but rather in long-term impairment of the organism's survivability , fecundity , or. Most plants produce secondary plant compounds, which are toxins used to protect the plant from insects and other animals that eat them, but some of which also work as medication for centuries in europe, older knowledge about the medical uses of plants was compiled in herbals—books that identified plants and their uses.
