Albizia is an herb that was originally grown in southern and eastern Asia. The flowers and stem bark are used to make medicine.

Albizia is taken by mouth for anxiety, cancer, depression, sleep problems (insomnia), and sore throat; to improve mood; and to reduce swelling associated with trauma.

Albizia is applied to the skin to treat insect bites, skin infections (boils and abscesses), ulcers, fractures, and sprains.

How does it work?

The chemicals in albizia have calming, sleep inducing, anticancer, and antioxidant effects.

More evidence is needed to rate albizia 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

It is not known if albizia is safe. But albizia might cause too much sleepiness.

Special Precautions & Warnings

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking albizia if you are pregnant or breast-feeding. Stay on the safe side and don't use it.

Surgery: Albizia might affect the central nervous system. It might increase the effects of anesthesia and other medications on the brain during and after surgery. Stop taking passionflower at least 2 weeks before a scheduled surgery.


Sedative medications (CNS depressants)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Albizia might cause sleepiness and drowsiness. Medications that cause sleepiness are called sedatives. Taking albizia along with sedative medications might cause too much sleepiness.

Some sedative medications include pentobarbital (Nembutal), phenobarbital (Luminal), secobarbital (Seconal), clonazepam (Klonopin), lorazepam (Ativan), zolpidem (Ambien), and others.


The appropriate dose of albizia 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 albizia. 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.
