Clinical Considerations
Passionflower is a gentle, calming nervine herb that most horses tolerate very well. It simply isn’t suitable for competing horses or pregnant mares, and care is needed if your horse is on heart or sedative medications.
Advisories
- Passionflower is a nutritional nervine that supports calmness and nervous-system balance.
- Suitable for short- or longer-term use as part of a stress, hormonal, or behavioural support plan.
- Beneficial for horses showing tension-linked digestive tightness, as passionflower supports gut–nerve regulation.
Contraindications
- Not permitted in competition. Passionflower is considered a controlled/banned substance due to its mild sedative and anxiolytic actions.
- Not recommended for pregnant or nursing mares because of historic caution with sedative and uterine-modulating botanicals.
- Avoid in horses with known bradycardia (slow heart rate) or unusually low blood pressure.
- Not suitable for horses with advanced liver disease without veterinary oversight, due to its mild hepatic metabolism involvement.
Competition Advisory
- Passionflower is now listed as a controlled/forbidden substance by most governing bodies (FEI, BE, BD, etc.).
- Always stop feeding well within the withdrawal window for your discipline.
Passionflower in History & Tradition
No doubt about it - no other herb wears beauty and serenity with such elegance as Passionflower, the ethereal bloom of Passiflora incarnata. Behind its intricate floral display lies a deep legacy of therapeutic calm - a nervine powerhouse long revered for its ability to gently soothe the nervous system, settle the heart, and support restful sleep.
Used across continents for centuries, Passionflower's specific affinity lies with neurological imbalances and the physiological fallout of mental tension - from panic and palpitations to tension-induced insomnia, spasms, and emotional burnout.
Its unique action is described not as sedative in the narcotic sense, but depressive in the true physiological sense- calming overactivity in the medulla oblongata , the brainstem structure that influences sleep, blood pressure, heart rate, digestion, and respiration. This gives Passionflower a very specific place in protocols for stress-exacerbated digestive disorders, emotional respiratory tension, and even neuro-visceral colic.
In traditional medicine, it’s described as supporting restorative sleep without residual dullness, allowing the body to enter parasympathetic mode naturally - like a gentle override switch for an overworked nervous system. A 2011 clinical trial (Ngan & Conduit) confirmed Passionflower’s benefits in improving sleep quality in healthy adults, even with only mild disruptions.
Passionflower’s calm also reaches the heart. By slowing the pulse and easing palpitations, it can offer grounding support during episodes of anxiety, nervous agitation, and emotional surges. A placebo-controlled clinical trial (Akhondzadeh et al., 2001) found it was as effective as oxazepam, a benzodiazepine drug, in treating generalised anxiety disorder - but without impairing work performance.
Herbalist Matthew Wood notes that Passionflower doesn’t induce drowsiness like a narcotic but rather helps “ cut out internal chatter, ” improving concentration while also enabling restorative rest - a dual benefit supported by later studies (Movafegh et al., 2008).
This adaptogenic nervine herb is now increasingly recognised in withdrawal protocols for benzodiazepines and opioids, due to its ability to bind to GABA, benzodiazepine, and opioid receptor sites(Wolfman, Dhawan, Nassiri-Asl). These properties make it a powerful ally for horses dealing with chronic stress, past trauma, or nervous system dysregulation.
