Chamomile vs Passionflower: The Calm vs The Sedative
If Chamomile is a gentle pat on the back, Passionflower is a firm hug.
They both work on GABA receptors. However, Passionflower (Passiflora incarnata) is significantly more potent for stopping "circular thinking" and inducing sleep.
| Feature | Chamomile | Passionflower |
|---|---|---|
| Strength | Mild | Moderate |
| Best Form | Tea | Extract / Capsule |
| Specific Benefit | Digestive Soothing | Circular Thinking (Looping thoughts) |
| Safety | Very High | High (May enhance sedative drugs) |
Mechanisms: GABA Modulation
Chamomile: The Light Touch
The apigenin in Chamomile binds weakly to benzodiazepine sites. It creates a feeling of well-being without heavy sedation.
What it means
It takes the edge off. You can drink it and still function.
Passionflower: The Heavy Hand
Passionflower contains chrysin and vitexin. These compounds bind more strongly to GABA receptors. It is comparable to low-dose oxazepam (a prescription drug) in some trials.
What it means
It effectively shuts down the brain's "worry loops." It is strong enough to make you feel drowsy.

For Upset Stomach
