Hyacinth bean is a climbing plant that produces seeds (beans). The seeds, pods, leaves, flowers, and roots are eaten. The seeds are used as medicine.

People take hyacinth beans by mouth to prevent pregnancy and for diarrhea and stomach disorders.

How does it work?

Hyacinth bean might prevent pregnancy by disrupting the lining of the uterus. It might also have antifungal and insecticidal activity.

Uses & Effectiveness

Insufficient Evidence to Rate Effectiveness for...

  • Birth control.
  • Diarrhea.
  • Stomach disorders.
  • Other conditions.
More evidence is needed to rate the effectiveness of hyacinth bean 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).

Side Effects

Hyacinth beans are POSSIBLY UNSAFE when eaten raw and in large amounts. Raw hyacinth beans contain certain chemicals, called cyanogenic glycosides, which can be poisonous.

Special Precautions & Warnings

Pregnancy and breast-feeding: Not enough is known about the use of hyacinth bean during pregnancy and breast-feeding. Stay on the safe side and avoid use.


The appropriate dose of hyacinth bean depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for hyacinth bean. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
