Abstract

Hericium erinaceus is an edible and medicinal mushroom commonly used in traditional Chinese medicine for centuries. Several studies have highlighted its therapeutic potential for gastrointestinal disorders such as gastritis and inflammatory bowel diseases. In addition, some components of this mushroom appear to possess strong antineoplastic capabilities against gastric and colorectal cancer. This review aims to analyse all available evidence on the digestive therapeutic potential of this fungus as well as the possible underlying molecular mechanisms.

Keywords: Hericium erinaceus; Fungus; Gastritis; Inflammatory bowel diseases; Gastric cancer; Colorectal cancer

Core Tip: Various natural and non-pharmacological principles have been used to treat gastrointestinal disorders. Hericium erinaceus is a Chinese mushroom with a centuries-old medicinal tradition. Several preclinical studies have demonstrated their anti-inflammatory and antineoplastic potential. The therapeutic activity of this mushroom also targets inflammatory bowel diseases, as demonstrated in several animal experiments. However, evidence from in vivo studies is not generally available for patients with gastrointestinal disorders. It is also unclear which component of this mushroom has the greatest potency and the best safety profile.
