What is Quassia?

Quassia is a plant. The wood is used as medicine.

Quassia is used for treating an eating disorder called anorexia, indigestion, constipation, and fever. It is also used to rid the intestines of various kinds of worms; as a tonic or purgative; and as a mouthwash.

Some people apply quassia directly to the scalp for lice.

Rectally, quassia is used for treating worm infestations.

In manufacturing, quassia is used to flavor foods, beverages, lozenges, and laxatives. The bark and wood have been used as an insecticide.

Insufficient Evidence to Rate Effectiveness for...

  • Lice. Early research suggests that applying quassia tincture one time can kill head lice. However, the lice might come back. Some research shows that two applications within one week might be more effective than a single application.
  • Appetite loss (anorexia).
  • Indigestion.
  • Constipation.
  • Fever.
  • Intestinal worms.
  • Other conditions.
More evidence is needed to rate the effectiveness of quassia for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
