Frankincense or boswellia comes from a flowering and fruit bearing tree. Frankincense can be taken in liquid, essential oil or pill form. This herb may be beneficial when used internally and can help with the treatment of stomach and intestinal ailments as well as help treat the symptoms of colds. However, frankincense should only be used under the supervision of a physician because it can cause side effects such as gastric pain, nausea and abdominal fullness.
According to Organic Facts, frankincense helps to promote your digestion instead of suppressing your symptoms like antacids do. Organic Facts reports that frankincense oil helps to speed up the secretion of gastric juices that helps you to digest food and move it through the digestive tract. This can help to relieve heartburn and stomach upset from overeating or food that is taking too long to digest. In addition, the University of Michigan Health System reports that boswellia does not cause stomach irritation or ulcers to develop when used. Only a few drops of frankincense essential oil mixed with water is needed to treat digestive ailments. However, more research needs to be done to prove the particular benefits of frankincense for digestion.
According to a study done by I. Gupta, A. Parihar and P. Malhotra, frankincense is helpful for those who suffer from ulcerative colitis. According to the "Physician Drug Reference for Herbal Medicines," frankincense helped to improve abdominal pain and loose stools in patients. Taking an internal dose of frankincense also helped reduce the appearance of mucus and blood in the stool. The "Physicians Drug Reference for Herbal Medicines" recommends taking a gum resin preparation of 350mg of frankincense three times a day for 6 weeks.
Frankincense can also be taken to help reduce chest congestion caused by a cold or flu.

This reduction of mucus helps relieve discomfort in the chest. In addition, Organic Facts reports that frankincense can also help to reduce nasal congestion. Yale University also notes the benefits of using frankincense internally stating that it helps to clear sinus and chest congestion.
