This is in response both to the ''Herbal Amphetamine Alternatives'' post and my own post on ''Inositol-the anti introvert drug''.
I want to clarify some findings. But first I must say that I am a little hesitant on this subject as I have no idea as to the potential of these herbs to cause addiction or psychotic-like symptoms.
2 herbs have been shown to enhance or augment the release of dopamine in various regions of the brain. This is NOT related to natural DRI's (Fructus Akebiae, Chaenomeles Speciosa). The herbs are: Salvia Miltiorrhiza, and Thunbergia Laurifolia.
Salvia Miltiorrhiza:

Thunbergia Laurifolia:

Both herbs appear to increase overall 'signal intensity' in various brain regions, including the nucleus accumbens. Remember there was an earlier post which documented that dopamine release in the nucleus accumbens is necessary for social reward.
What appears promising about these herbs is that, in addition to their effects on dopamine, they are also quite potent antioxidants and toxin-antidotes. Also, although they appear to mimic cocaine/amphetamine to some degree, they take longer to have an effect, or have a longer-more prolonged release time. This suggests that may not have the same risk as synthetic forms.
So for treatment-resistant cases of behavioural inhibition, or even for street-drug stimulant addiction, these herbs may be a very promising treatment.
Open to discussion.
