The other therapeutic uses of the prickly ash include its application to treat disorders such as the dry mouth, tooth decay and toxic shock syndrome or circulatory failures caused by toxins. In addition, the prickly ash or medications prepared with the bark or berries of the tree are useful in relieving gas, curing diarrhea and toning up or neutralizing the digestive system.

In addition, the prickly ash bark was used by them to induce the secretion of saliva and cure various other ailments. During the end of the 19th century, eclectic doctors (physicians who chose the best or preferred medication from a variety of sources) practicing herbal medicine in the United States carried on with the conventional use of the prickly ash as the key medication to treat digestive disorders, reinforce the nervous system as well as cure cholera. At the same time, herbalists intensively used the bark of prickly ash to treat rheumatic conditions. Considered to be an alternative in traditional herbal medication, the prickly ash is known to improve the body's aptitude to combat as well as recover from all kinds of physical problems.
