Hericium Erinaceus (Lion's Mane Mushroom) has long been treasured in Japan and China as an important medicinal mushroom to heal gastric diseases. As a highly prized medicinal mushroom Japanese scientists have studied Hericium and have confirmed many diverse and important biological activities. In China, the hot water extract of Hericium reaches far higher achievement that it has been approved by the Ministry of Health to be a drug to treat gastric ulcer. Recent research indicates that the hot water extract of Hericium stimulates the synthesis of Nerve Growth Factor (NGF) and promotes the process of myelination. Increased production of NGF may enhance cognitive functions and help to slow the onset of dementia associated with various neurological conditions. Hericium Erinaceus extract is produced from the same Hericium that is used by Chinese pharmaceutical industries to produce Hericium extracts for local hospitals and is manufactured to a higher standard than the published standard by Chinese Ministry of Health.
