The Benefits of Caraway Oil and Peppermint Oil

Nonprescription FDgard® is specially formulated with a combination of caraway oil and peppermint oil (primary component: l-Menthol). Clinical studies have shown that this combination of ingredients can help manage the syndrome of FD symptoms.1 But how exactly do these ingredients combine to produce calming digestive results? Through the science of dual and synergistic action!

Caraway oil is intended to serve as a fundus relaxant. The fundus is the upper-most part of the stomach. It stores undigested food and gases that are released during digestion. In order to accommodate these materials, the fundus must adapt (relax). According to one study, impaired fundus accommodation was found in 40% of Functional Dyspepsia cases.2

L-Menthol, the primary component in peppermint oil, acts as an analgesic for pain and cramp reduction. Its antispasmodic function combines with the fundus relaxant caraway oil, resulting in synergistic action. Put another way, these ingredients are designed to work together and separately to encourage the natural movement of food through the digestive tract.3 Functional Dyspepsia is largely a disorder of movement, meaning the stomach does not expand normally in response to ingested food. The ingredients found in FDgard are specially formulated to target the site of digestive disturbance to restore the natural rhythm of the digestive system.
