Passiflora incarnata
Passionflower for Dogs
Supports relaxation and emotional balance

Passiflora incarnata (passionflower) for calm behaviour in dogs
Passionflower's traditional use for relaxation now has mechanism research behind it, and it acts on a different pathway than Camellia sinensis, which is why the two are combined rather than used alone.
A long history, now backed by mechanism research
Passionflower has been used traditionally for relaxation for a long time, well before there was any research explaining why it might work. More recent studies have looked at its interaction with nervous-system pathways involved in stress response and restlessness, giving that traditional use a plausible biological basis.
A 2020 systematic review of Passiflora incarnata in neuropsychiatric contexts summarised this evidence, and an earlier controlled study specifically measured anti-anxiety effects from Passiflora extracts.
Why it sits next to green tea in the formula
Passionflower and Camellia sinensis's L-theanine are thought to act on related but not identical mechanisms, both connected to calm behaviour and nervous-system balance. Combining the two in Calm is a deliberate attempt to support a calmer baseline from more than one direction, rather than depending on a single compound to do all the work.
