Equilin is an estrogen from horses. It is one of the estrogens present in the mixture of estrogens isolated from horse urine and marketed as Premarin. Premarin became the most commonly used form of estrogen for hormone replacement therapy in the United States of America. Estrone is the major estrogen in Premarin and equilin is present as about 25% of the total. Estrone is a major estrogen that is normally found in women. Equilin is not normally present in women, so there has been interest in the effects of equilin on the human body.

Coumarin is a pleasantly fragrant chemical compound found in many plants. It is used in the pharmaceutical industry as a precursor molecule in the synthesis of a number of synthetic anticoagulant pharmaceuticals similar to dicoumarol, notably warfarin and some even more potent rodenticides that work by the same anticoagulant mechanism. It has been used in the treatment of lymphedema and also used as aroma-enhancer in pipe tobaccos and certain alcoholic drinks, although it is generally banned as a flavorant food additive, due to concerns about hepatotoxicity coumarin causes in animal models. It is also used as a gain medium in some dye lasers.
