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.

Not in this cupboard

Do not brew these

Pennyroyal

Hedeoma pulegioides / Mentha pulegium

Gas plant

Dictamnus albus

Strong phototoxicity: sap plus sun can blister and stain the skin for a long time. Internal use has been tied to liver injury. No established tea dose. Not in this cupboard.

29 promised teas

Caution

Cayenne

Capsicum annuum

Sharp heat, fruity-pepper, then a slow burn. A pinch in a cup is plenty.

Caution

Clove

Syzygium aromaticum

Hot, sweet-numbing, dental and festive. One bud flavors a cup.

Caution

Garlic

Allium sativum

Sulfur, heat, then sweet if cooked. Raw in honey is fierce; broth is kinder.

Caution

Sage

Salvia officinalis

Earthy, savory, slightly bitter and camphor, warm and distinctive.

Caution

Caution

Celery seed

Caution

Kelp

Laminaria spp.

Ocean, iodine, brine. A flake, not a handful.

Glycyrrhiza glabra

Distinctly sweet, anise, earthy, a little woody. Sweet even without sugar.

Caution

Fenugreek

Trigonella foenum-graecum

Maple syrup or burnt sugar with bitter, celery-seed, savory undertones. Strong and unmistakable.

Caution

Caution

Horseradish

Armoracia rusticana

Sinus-clearing heat, mustard-tear, then sweet root. A scrape, not a tea.
