Storax is an oily resin (balsam) from Liquidambar orientalis or Liquidambar styraciflua tree trunks. The wood secretes storax when the bark is damaged.

Storax contains chemicals that might have antibacterial effects and reduce swelling. It's obtained by scoring the outer tree bark, then boiling the inner bark in water, and then pressing the inner bark in cold water.

People use storax for stomach pain, eczema, common cold, cough, diarrhea, epilepsy, wound healing, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse storax with other products that are also commonly called liquid amber, including succinate and St. John's wort. These are not the same.
When taken by mouth: Storax is commonly consumed in foods. It is possibly safe when used in appropriate amounts as medicine. Side effects might include diarrhea and rash. But taking large amounts of storax is possibly unsafe and may cause serious side effects.

When applied to the skin: Storax is possibly safe when used on small areas of skin. But it is possibly unsafe when applied to open wounds. This may cause serious side effects, such as kidney damage.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if storax is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.


There is interest in using storax for a number of purposes, but there isn't enough reliable information to say whether it might be helpful.
