SinuCheck ^® provides a pure form of eucalyptus oil that has been clinically shown to support sinus and respiratory health.† The oil extract contains at least 95% cineole, the key compound in eucalyptus, in an enteric coated softgel capsule.

Enteric coating ensures the capsule passes through the stomach unchanged and opens in the small intestine where cineole can safely and effectively be absorbed. Clinical research has shown that this purified extract is well tolerated when used as directed.

In contrast, whole eucalyptus oil contains a number of different substances from a variety of eucalyptus species – some of which do not contain cineole. As such, eucalyptus oil and purified cineole will not have the same pharmacological and toxicological characteristics. While some medical resources urge caution when using eucalyptus oil internally as it can irritate the lining of gastric mucosa, this same caution is not warranted for enteric coated cineole supplements, such as SinuCheck ^®.
