Passiflora incarnata is also known as maypop, purple passionflower, true passionflower, wild apricot, and wild passion vine.
- Anticonvulsant: hydroalcoholic extract of P. incarnata at a dose of 0.4 mg/kg not only prolonged the onset time of seizure but also decreased the duration of seizure as compared to the saline group.
- hydro-ethanolic extract of P. incarnata suppressed seizures induced by the drug, pentylenetetrazole. The extract also ameliorated the postictal depression associated with the convulsant drug.[1:1]
- Anxiolytic: The hydroalcoholic extract demonstrated antianxiety effects.[1:2]
- Sedative: aqueous extract demonstrated sedative effects.[1:5]
Disease / Symptom Treatment
- Dysmenorrhoea: has been used to treat painful menstruation, typically involving abdominal cramps.
- Neurological Disorders:
- Anxiety: The benzoflavone moiety derived from the methanolic extract of P. incarnata dem- onstrated significant antianxiety activity.[1:6]
- Opioid/Opiates Withdrawl: The methanolic extract of P. incarnata has been shown to delay the development of a tolerance to the analgesia of the opium alkaloid, morphine.[1:9]
- A single dose of methanolic extract of P. incarnata resulted in a decrease of naloxone-precipitated withdrawal symptoms in mice which have been made tolerant with chronic administration of morphine.[1:10]
- Passiflora included with clonidine treatment for opioid withdrawl showed distinctly superior improvements of mental symptoms.[1:11]
