Western hemlock

Tsuga heterophylla

A large conifer with a drooping top and short, flat needles. The bark is very rich in tannins; the young needles contain vitamin C.

Safety notes

Not to be confused with poison hemlock (Conium), a very poisonous herb that is also called hemlock in English. Not in pregnancy. Traditional use is no proof of effect; consult a doctor or pharmacist if you are pregnant or breastfeeding, take medication or have a medical condition.

Cautions by tradition (1)
  • Kwakwaka'wakw medicine: Do not confuse with poison hemlock. Not in pregnancy.

Preparation

Pound root bark lightly and leave it in water overnight until the water is red; use as a wash for sores. Young needles as a tea.

Use in traditions

For a sore or burn that would not heal, a Kwakwaka'wakw man scraped the rough bark off a root, shaved off four pieces of bark and pounded them gently between two stones. He left them overnight in water in a large shell; in the morning the water was red. With it he washed the sore morning and evening. A child with a sore throat or sore gums kept a folded piece of bark in its mouth. For diarrhoea the root bark was boiled with juniper and two ferns. Other peoples ate the inner bark in times of famine.
