(Artemisia absinthium L)


Wormwood is mainly used as a bitter tonic. Chances are that you have heard of the ancient proverb ‘bitter as wormwood.’ Its this bitter characteristic that gives wormwood its significant place in herbal pharmacopeia. As the name implies, wormwood is a powerful worming agent that has been historically used to expel parasites including tapeworms, threadworms, and roundworms from dogs, cats, and people. Wormwood can be taken in the form of capsule, tea, or extract.

Although the bitter principle in wormwood is largely nontoxic, just as it makes the life miserable for intestinal parasites, it can be harsh on the host. Contraindications should be carefully studied before using the herb and as always it is best to use it under the guidance of a health care practitioner.

Wormwood earned a bad reputation caused by confusion over the fact that an alcoholic drink called absinthe used to be made from parts of the wormwood plant. This drink was very strong and often abused thereby damaging the reputation of the entire herb. This drink is no longer produced.


  • The azulenes in the plant are anti-inflammatory and reduce fevers.
  • The bitter components of wormwood make it an excellent remedy for digestive issues including hypochlorhydria. This is primarily because a bitter flavor on the tongue actually causes the gallbladder to produce and release bile. Contrary to popular belief, it is often too little acid production that leads to indigestion, not an excess of it.
  • It can help boost energy.
  • It is also noted as being useful in alleviating fever.
  • It is effective in expelling parasitic worms like roundworm from the digestive tract.
  • It may be applied topically to reduce inflammation of insect bites and promote healing.
  • Wormwood is also noted to be useful in treating jaundice, a sign of liver dysfunction and to increase sexual desire.

Wormwood is very bitter in taste and this bitterness is one of the key reasons for its success as an anthelmintic herb as it can literally drive out some of the worms and parasites. At the very least it makes it unpleasant for these critters to live inside you. It is best to use wormwood capsules (preferably thujone-free) instead of brewing your own tea because of the plant’s intoxicating characteristic.

Wormwood is also highly valued, especially for its tonic effect on the liver, gallbladder and digestive system. It increases stomach acid naturally, improving digestion and the absorption of nutrients. It also eases wind and bloating and, if taken regularly, can help the body return to full vitality after a prolonged illness. It can be taken as either capsules or tea; however it is recommended to take it as a tea since its bitter taste on the tongue is what actually causes the gallbladder to produce and release bile.

  • The FDA lists wormwood unsafe for internal use due to the toxicity of thujone oil which should never be used apart from the whole herb.
  • Wormwood should always be used in dried form for teas which contain little if any of the volatile oil. The bitter principle in wormwood is largely nontoxic.
  • Taking too much wormwood can cause diarrhea because it stimulates swift emptying of the intestines as a part of its tonic effects.
  • It should not be used at all in animals with liver disease.
  • Essential oil of Wormwood is a potent poison due to high concentration of thujone in it. It is actually a neurotoxin so extreme care needs to be taken while using it.


Wormwood tea is made from an infusion of fresh or dried leaves but it is best to use in dried form since it contains little if any thujone.

The best time to collect leaves and flowers of wormwood is on a warm, sunny day after blooming has begun in July. These parts are then dried in partial sun at 70 degrees F or more. Once dried, one ounce of dried leaves can be steeped for 10-12 minutes in one pint of boiling water.
