Reflux Fix product combo includes:

Absinthium - The herbs found in Absinthium are used for acute and chronic gastrointestinal symptoms: heartburn, acid reflux, indigestion, lack of appetite, flatulence, inflammation, meteorism and dyspepsia.
This herbal combination normalizes the digestive gastric juices (namely hydrochloric acid and digestive enzymes) and motility conditions by influencing the autonomic tonicity. It has a direct and indirect influence on the mucous membranes with an anti-inflammatory effect and mobilization of the protective mucosa. With use, a general tonification with improvement of circulation in the GI tract can be expected.

Basictab - For acid-base (pH) balance in the body. It is used for inflammation, heartburn and indigestion, allergies and allergic reactions, detoxification and as prevention and supportive therapy in many chronic degenerative conditions. Acid-base balance is important to promote a favourable intestinal environment to prevent candida overgrowth, improve digestive processes and support beneficial intestinal flora.

Recommended dose see the heartburn and acid reflux protocol guide.
