After stopping centrum energy (contains ginseng extract 40 mg), I have taken folic acid 1 mg daily at night after the meals. I am not taking any other drug/supplements. After stopping centrum energy, I have taken ginger coffee (added commercial ginger paste to coffee) morning and evening for two days. This caused left sided headache suggesting decreased serotonergic neurotransmission. After I stopped ginger intake, that headache disappeared. Taking ginseng for 1 month might have caused increased serotonergic neurotransmission.
Positive effects (probably due to increased doapminergic neurotransmission secondary to disinhibition by serotonergic neurotransmission):
1. Increased speed of brain processing - I am able to read complex things and understand better and able to remain focused in a long conversation (more than 1 hour). I am able to do things at a faster rate.
2. Decreased post lunch sleepiness
3. Increased libido and strong erections
4. Increased loudness of voice and no hoarseness of voice even after talking for long time.
5. Decreased mucous formation in nose while eating. This increased mucous formation happens whenever I eat lunch despite the food is not spicy and hot. This increased mucous formation may be due to increased cholinergic drive secondary to disinhibition by dopaminergic neurotransmission.
Negative effects:
1. Slight stuttering
2. Slight feelings of stress
3. Increased cold feeling - reduced tolerance to cold climate
