Is there a potential of misuse for Magnolia officinalis compounds/metabolites?

OBJECTIVE

Magnolia bark contains magnolol, metabolized to tetrahydromagnolol and honokiol, with both GABA-ergic/cannabimimetic activities, hence of possible attraction to vulnerable individuals/recreational misusers.

METHODS

A literature review, assessment of related anecdotal online Magnolia misuse's reports and an overview of Magnolia products' online acquisition possibilities has been here described.

RESULTS

No peer-reviewed papers about Magnolia abuse/misuse/dependence/addiction were identified. Conversely, from a range of websites emerged potentially 3 groups of Magnolia misusers: (a) subjects with a psychiatric history already treated with benzodiazepines, being attracted to Magnolia bark as a "natural sedative"; (b) polydrug misusers, ingesting Magnolia with a range of other herbs/plants, attracted by the GABA-ergic/cannabimimetic activities; (c) subjects naive to the misusing drugs' scenario, perceiving Magnolia as a natural dietary supplement/weight-control compound.

CONCLUSIONS

To the best of our knowledge, this is the first paper commenting on the possible Magnolia derivatives' potential of misuse. Magnolia's recent increase in popularity, mainly as a sedative, may be arguably due to its peculiar pharmacological properties/acceptable affordability levels/virtually worldwide favorable legal status and customers' attraction to a product being perceived as "natural" and hence somehow "safe." Future/potent/synthetic magnolol and honokiol structural analogues could however contribute to increasing the number of synthetic GABA-ergic/cannabimimetic misusing compounds.
