Christopher Hobbs:
“Adding a few fresh or dried leaves to beans while cooking is said to help eliminate gas. The seed is used in traditional Mexican medicine to rid intestinal parasites. The oil extracted from the seed was formerly used to treat pinworms but is highly toxic. A mild tea from the seeds or leaves is safe when used under the guidance of an experienced herbalist.”
Historical Uses
Wormseed has been used for centuries in various cultures, especially in Central and South America. Traditionally, it was employed to treat parasitic worm infestations, digestive disorders, and to induce abortions. It was also used for treating colds, fevers, and as a purgative.
Modern Clinical Uses
- Herbalists/Naturopaths: Wormseed is mainly used to expel intestinal worms, especially roundworms and tapeworms. It is also utilized for digestive issues like bloating, gas, and indigestion, and occasionally for respiratory conditions like asthma and coughs.
- Chemistry/Pharmacology: Wormseed contains essential oils (including ascaridole, a potent active compound) that have demonstrated anthelmintic, anti-inflammatory, and antimicrobial properties. It also has antioxidants and could support liver health.
Clinical Trials
Clinical trials on wormseed are limited. However, research has supported its efficacy as an anthelmintic agent. Studies on its active compounds, especially ascaridole, show potential for treating parasitic infections. Some trials have also noted its effectiveness against intestinal protozoa. Yet, due to safety concerns, most trials are cautious about recommending high doses for long-term use.
Summary
Wormseed is a traditional remedy with a history of use for treating parasitic worms and digestive disorders. It has modern applications in herbal medicine, particularly for worm infestations, but due to its toxicity in high doses, caution is required. Further clinical trials are needed to establish clearer safety guidelines and therapeutic recommendations.
