"Lion's mane mushrooms, known scientifically as Hericium erinaceus have quickly risen to fame on social media and are often promoted in tea and supplements. Imagine fluffy white pom-poms or, of course, the mane of a lion—that's what they look like! These mushrooms add visual appeal but beyond their appearance, they're believed to be packed with compounds that have antioxidative, anti-inflammatory, antimicrobial and cardio-protective properties.
Interestingly, there's growing research suggesting lion's mane mushrooms could offer cognitive benefits, potentially helping in the treatment of early Alzheimer's disease. A small 2020 study saw 49 participants, who were 50 years old and above take either lion's mane capsules or identical placebo capsules for almost a year. The study included cognitive assessments, blood tests and neuroimaging and found that those taking lion's mane showed significant improvements in their Cognitive Abilities Screening Instrument (CASI) and Mini-Mental State Examination (MMSE) scores, as well as in their daily living activities, compared to the placebo group." - From lion’s mane to chestnut, are mushrooms the key to good health? - BBC Food
