Bitters are compounds which influence many areas of upper digestive function including salivation, gastric secretion, bile flow and pancreatic function, and can be consumed via foods or as herbal medicines (also known as bitter tonics, aromatic digestives and digestive stimulants).
It is thought that by stimulating the bitter taste receptors in the mouth, these compounds in turn stimulate, via the vagus nerve, the production of the hormone gastrin which activates gastric juices. The results can include increased hydrochloric acid production; increased digestive enzyme and bile production; increased motility; increased appetite and overall improved digestive function.
Mental and physical fatigue and general weariness resulting from stress are common symptoms in patients I see. Their busy, fast paced lives, often balancing work, study and parenting leave them exhausted and frustrated, with a lack of motivation and energy.
In chronic stress - hormone balance, blood sugar metabolism and immune function are frequently impaired, and in addition to fatigue, other common symptoms can include aches and pains in muscles and joints, menstrual irregularities, digestive and sleep disturbances and hypersensitivity to stimuli such as noise and smell.
