The cup

The promise on tea

A cup is a promise. These ratings, flavors, and asterisks are the house rule — drawn from herbal literature and safety reviews, written for this stillroom. Not a diagnosis. Not a prescription.

How to read the house

  • Safety depends on the right plant, the right part, the right pot, the dose, the duration, and the body that drinks it.
  • Pregnant, nursing, on medicine, or unwell — ask a clinician before a regular cup.
  • Misidentified wild plants can kill. When in doubt, do not drink.
  • A kitchen pinch is not a medicinal extract. The oil is not the leaf.
