Each liquid drop contains Dopamine, L-dopa, Melatonin and Serotonin, all in 6x, 12x, 30x, 12c and 30c. Also included are two drainage substances, Taraxacum and Hydrastis in 3x. DOPAMINE: An extremely important inhibitory neurotransmitter. Helps three main dopamine neurotransmitter systems: Extrapyramidal system: Involves coordination and integration of fine muscular movement. Mesollmbic system: Involves control of memory and emotion. Hypothalamic system: Pituitary axis is involved with such endocrine related activity as the release of prolactin which induces lactation in mammals. L-DOPA: Neurotransmitters of the brain, the precursor of Dopamine. Melatonin: A hormone of the Pineal Gland. The Pineal Gland forms Serotonin, which forms Melatonin. It is a neuroendocrine transducer that responds to light stimulation. Used for Seasonal Affective Disorder, compulsive depressive disorder and jet-lag. SEROTONIN: The neurotransmitter of primary importance in brain chemistry. It is responsible for both appetite and sleep control and when deficiencies occur; aggression and obsessive-compulsive disorders may manifest themselves. Used for appetite, insomnia, depression and suicidal tendencies. TARAXACUM: A liver remedy which acts to improve neurotransmitter effectiveness through its ability to enhance drainage. HYDRASTIS: Hydrastis also functions as a general drainage remedy.
