Dopamine is a Hormone and Neurotransmitter occurring in a wide variety of animals including both vertebrates and invertebrates Prolactin ( PRL) or Luteotropic hormone ( LTH) is a Peptide hormone primarily associated with Lactation.
Examples include Domperidone & Metoclopramide (synthetic), sweet potato, silymarin, and fenugreek (plant-derived), and prolactin (endogenous). Domperidone (trade name Motilium or Motillium) is an Antidopaminergic drug, developed by Janssen Pharmaceutica, and used orally Metoclopramide ( INN) (ˌmɛtəˈkloʊprəmaɪd or /ˌmɛtəˈklɒprəmaɪd is a potent Dopamine receptor antagonist used for its Antiemetic and Prokinetic The sweet potato ( Ipomoea batatas) is a Dicotyledonous plant which belongs to the family Convolvulaceae Silibinin ( INN) also known as silybin, is the major active constituent of silymarin, the mixture of flavonolignans extracted from blessed milk thistle Fenugreek ( Trigonella foenum-graecum) is a plant in the family Fabaceae.
