The oestrogens are named for their importance in the oestrous cycle. (ChEBI). Estrogen is found in date and apricot.

These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids.

Anti-acromegalic 82 Anti-hemorrhagic 321 Drug that acts on blood and blood-forming organs and those that affect the hemostatic system. Anti-menopausal 429 Any substance introduced into a living organism with therapeutic or diagnostic purpose. Antitumor 672 A substance that inhibits or prevents the proliferation of neoplasms. Cardioprotective 769 A drug used for the treatment or prevention of cardiac arrhythmias. Anti-arrhythmia drugs may affect the polarisation-repolarisation phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibres. HDL-genic 969 Immunostimulant 1032 A substance that augments, stimulates, activates, potentiates, or modulates the immune response at either the cellular or humoral level. A classical agent (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contains bacterial antigens. It could also be endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Its mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy is related to its antigen-specific immunoadjuvanticity. LDL lytic 1066
