Mushrooms and Health


The legendary toxicity of certain mushrooms is well known. The Death Cap, a deadly species, is still too often confused with other species and eaten. It is one of three deadly Amanita species which are responsible for more than 90% of deaths linked to the consumption of mushrooms.

From a medical point of view, mushrooms don't only have beneficial effects. They are implicated in numerous dermatological conditions and infections (eg thrush, athletes foot).

Due to their metabolic richness they have great pharmacological potential. The historic (and accidental) discovery of antibiotics by Alexander Fleming from strains of Penicillium is famous.

What we no longer know is the centuries old use of certain species in the Chinese pharmacopia, such as Lingzhi Mushroom, which has demonstrated results recently.

Effectively, lentinane and other polysaccharides found in abundance in mushrooms directly stimulate the immune system.

Oyster mushrooms have effects even more impressive on the regression of cancerous cells (at least in the lab).

I have met this man... he is a friend of Jim the Mushroom Man.
He, Jim and one other were involved in creating a specialist, organic mushroom growing medium... and also a honey, mustard and unnamed fungus mix to be sold as an herbal ointment... the latter enterprise never took off... the growing medium, which I think Mr Zhang was responsible for, is a winner... the main factory is in Belgium and overseen by Jim's son.
And I love those eryngii... lightly fried and served on brown toast!

Mr and Mrs Zhang are lovely people. Thanks for the extra tidbit of info about him that I didn't know.

Pauline and I were very surprised to find Jim here... he had stopped selling from Leeds farmers' market and just supplied restaurants and specialist shops... we go to an event at Beaulieu les Loches and there he was with Phillipe... selling and promoting the mushrooms they were growing, using the bio medium, in the old Champion caves... sadly Jim had to give up... he developed a lung problem working in the damp in the caves. We've now lost touch again... but Jim learnt all he knew about 'shrooms from Phillipe and the very tall Swedish(?) gentleman right here in Loches!!

I read and then forward all such posts to my son, an environmental scientist, botanist, and mushroom aficionado in the Appalachians in North Carolina. He loves finding correspondences between French and New World varieties. Like me, he is also keen on Preuilly. Thank you!

The 'Swedish' gentleman is Hendrick and he's Dutch but has lived here for years. He actually lives and mushroom farms in Selles sur Cher. He's also at Amboise market as well as Loches, selling mushrooms.

Your son sounds like just my sort of person! Thanks for sharing the blog and we love hearing that people are appreciating it.
