Ghana seeds are the dried seeds of the Ghanaian grain Griffonia simplicifolia, a leguminous shrub, and are native to West African countries such as Ghana, Côte d'Ivoire and Togo. Ghana seed plants can generally grow to a height of 2 to 3m, with brown-black and smooth branches; in secondary forest areas, some grow on tall trees. Flowering period from August to October, the flowers (hermaphrodite) are light green, and bear fruit from December to February of the following year. The pod usually has 1 to 4 seeds. The mature seeds are oblong, about 1.5cm in length and 1cm in width. The seed coat is black, wrinkled, endosperm yellow-green, and slightly bean aroma. Since ancient times, the folk medicine in West Africa has used the leaves of Ghana seeds to recover wounds. The leaves of the leaves are a good medicine for treating urinary tract disorders and kidney diseases.

1. Antidepressant effect
The experiment observed the utilization of TRP (tryptophan) in patients with depression, and found that the utilization of L-TRP in patients with major depression was significantly lower than that in patients with mild depression.
2. Central analgesia
TRP may exert a central analgesic effect by increasing the content of 5-hydroxytryptamine (5-HT) in the central nervous system. After the 5-HT descending fibers in the brain reach the spinal cord, they can be mediated by interneurons to activate enkephalin neurons in the posterior keratinocytes, and the latter can inhibit the transmission of peripheral pain information to the second level by means of presynaptic inhibition. Neurons, which play a central analgesic effect.
3. Cardiovascular system impact
The results of studies on different hypertensive animal models in rats show that 5 htp powder also has anti-hypertensive activity.
4. Hypnosis
5-Hydroxytryptophan can use vitamin B6 to generate serotonin, the precursor of the nerve hormone, to promote sleep and mental stability.
5. Physiological effects of anti-stress
Studies have found that injection of 5 htp powder can reduce the mutual attack and killing of mice in a short period of time, and the degree of reduction is proportional to the amount of 5-hydroxytryptophan injected.
6. Influence on neuroendocrine activity
5-Hydroxytryptophan can not only be converted into some hormones to directly participate in endocrine activities, but also into the central neurotransmitter 5-hydroxytryptamine, which indirectly affects the release of neurohormones.
7. Suppress appetite
3-200mg·kg-1 dose of 5-hydroxytryptophan can cause rats to produce anorexia which is positively correlated with the dose.
