Jasmine Flower Extract Lowers Prolactin

Randomized Controlled Trial

Jasmine Flower Extract Lowers Prolactin

Philip Finny et al. Trop Doct.


Background: Antipsychotic drugs frequently cause amenorrhoea and galactorrhoea. Jasmine flowers used topically were as effective as oral Bromocriptine in suppressing puerperal lactation. This study aims to evaluate the efficacy and safety of intranasal jasmine flower extract (JFE) to reduce prolactin levels of patients on stable doses of antipsychotic drugs.

Method: This is a randomized, double blind, crossover clinical trial. An aqueous-ethanol extract of jasmine flowers was prepared and used as nasal drops. A decrease in serum prolactin of ≥25 ng/mL was considered a significant response.

Results: Ten out of 35 women had a significant drop in the serum prolactin while on the JFE. The non-responders to JFE were on higher doses of antipsychotic drugs. The main side effect was a transient and mild burning sensation in the nose. A cost analysis favoured JFE over dopamine agonists.

Conclusion: JFE contains a prolactin-lowering substance which needs further characterisation.

Keywords: Jasmine flower extract; antipsychotic medication; hyperprolactinaemia.
