No. The actives are inactive until your gut bacteria convert them, gradually, over 8–10 hours. The tea works with your night, not against it. The trigger is your first meal or drink in the morning.

That's the design. Relief follows your first meal or drink — at home, before the day starts. Not during it.

As strong as you leave it in. Three minutes is gentle, five is standard, seven is the ceiling. One sachet covers the whole range — you never need a second product.

It's for occasional constipation — use it for the episode, not forever. Most episodes need one to three nights. If you're reaching for it beyond two weeks, talk to your pharmacist; something else deserves attention.

Herbal and mild. Chamomile, fennel, coriander and peppermint round the senna — drink it like any evening tea.
