General Info:

Lion's Mane (Hericium erinaceus) is one of the most famous mushrooms in oriental history and has been traditionally used as medicinal mushroom in China and Japan for centuries. 

Lion's Mane is also known as Monkey Head or Bear's Head thanks to the
beautifully cascading long white tendrils hanging down from the solid
rubber-like base. In China it is called Houtou, in Cantonese it is Hous Gu. 
In Japan it is called Yamabushitake because of the resemblance to the ornamental cloth worn by monks, Yamabushi. Its English common name is Hedgehog Fungus.

Legend tells us that the ones that regularly consume this mushroom
would have the steel nerves and memory of a lion.

This magnificent mushroom grows off the recently fallen deciduous 
broad-leaved trees, mostly oaks. Its white flesh is slightly ice-like translucent and rubbery when touched. The base is strongly attached to the tree trunk and it is difficult to remove it without the use of a sharp knife. 

Lion's Mane is not just an edible mushroom, it is regarded a culinary 
delicacy and one of the four most famous Chinese dishes. The secret 
is to pick the mushroom at the right time. When prepared the texture 
reminds one of an octopus, squid or a lobster. It is delicious when sty-fried with oyster sauce or chopped cold in a salad with sesame 
oil and seaweed. 

It has a rubbery texture if it is picked and cooked when too young; 
if too old it develops an unpleasant sour taste. Exquisitely enjoyable
when prepared at the prime time.

The most outstanding and most valuable property of Lion's Mane is 
its ability to stimulate the synthesis of Nerve Growth Factor (NGF) and promote the process of myelination. Increased production of NGF may enhance cognitive function and help to slow down the onset of dementia, brain dysfunction associated with Alzheimer's disease and various other neurological conditions. Nerve Growth Factor (NGF) is effective in prevention of nervousness, forgetfulness and early aging process. 

Numerous studies confirm a number of traditionally known beneficial 
properties of Lion's Mane in supporting and regulating the function of the digestive system and its tonic effect on the nervous system.
 
Clinical trial tests reveal that Hericium Erinaceus polysaccharides-HEP
is effective as anti-tumour natural product by enhancing various immune system functions rather than attacking the tumour cells directly. 

Studies confirm many of Lion's Mane traditional uses, such as supporting 
the function of cardiovascular system, lowering blood pressure and serum cholesterol, strengthening the respiratory system, acting as a digestive tonic when indigestion and constipation problems occur.
