Passiflora incarnata Harmans

It is, however, a recognized component of the extracts of the passion flower Passiflora incarnata, but the much more plentiful inventory of flavinoids present in this marvelously named plant seem to be the agents that are responsible for its sedative properties. Again, harman is probably not an active contributor to the reported pharmacological action. In fact it has been spotted as a component of cigarette smoke, and here it certainly cannot be a factor that contributes to the virtues of smoking.
