What is gastritis?

Gastritis is a general term used to refer to a group of diseases that have one thing in common, inflammation and erosion in the lining of the stomach. The inflammation can caused by the same bacterial infection that causes stomach ulcers, and can also be caused by frequent use of certain painkillers, and over consumption of alcohol.

Gastritis can occur suddenly (acute gastritis) or occur slowly over time (chronic gastritis). In some cases, gastritis can cause ulcers and an increased risk of stomach cancer. However, for most people, gastritis is not serious and improves quickly with treatment.

With this health issue, it’s important to focus on bringing the inflammation down whilst repairing the gut lining.

What mushrooms can help you in gastritis?

Lion’s mane

Anti-inflammatory and prebiotic properties
Several studies have shown the gastroprotective effect of lion’s mane on the digestive tract. This is mainly due to its anti-inflammatory and prebiotic effects. The mushroom helps to repair damaged gastric and intestinal mucosa, showing great benefits  in esophagogastric pathologies, such as gastritis and ulcer.


A significant number of people can develop gastritis due to contracting the Helicobacter pylori bacteria. In that case, it is important to remove this bacteria from the gut. Reishi extracts have shown to inhibit the growth of H. pylori. The bioactive compounds present in Reishi have many properties, including those related to the supporting gastric ulcers and reducing  inflammation.
