From cordyceps to lion’s mane, shiitake, maitake and everything in between – the Shroom Boom of the last few decades is showing no sign of halting any time soon.
While mushrooms have long been used for healing purposes in Chinese medicine, their health-boosting benefits are only just being promulgated within the Western world. We’re no strangers to fungi being used in healthcare – penicillin, after all, is a type of mould. Yet incorporating specific mushrooms which target particular health concerns into our daily diets through varied supplementation is changing the way we approach wellness.
Chaga is a special, rather innocuous-looking mushroom that grows on the trunks of birch trees. Foraging novices will find that it’s easy to miss due to the fungus’ woody, almost burnt appearance which – especially in north and northwestern Pacific climates – might simply be mistaken for forest fire charring. Breaking open chaga growth, however, will reveal its bright and spongey orange-brown core.
The burnt charcoal-resembling fungus is often referred to by nootropic enthusiasts as the ‘diamond of the forest’, for its overwhelming number of potential health benefits. But what exactly are they, and how can one ensure that they’re getting the most from their chosen chaga supplementation?
The benefits of chaga explained
Before we get into the potential benefits of chaga mushrooms, we urge our readers not to exalt the latent health benefits of fungi and mushroom supplementation over the advice of medical doctors. If you are concerned about your health or are experiencing worrying symptoms, contact your GP or call the NHS helpline on 111.
- Immune and anti-inflammatory support: Chaga may help to regulate the production of cytokines (a broad and loose category of small proteins important in cell signalling and inflammation control). This, in turn, may support the body’s immune system by helping cells communicate better.
- Antioxidant support: Chaga mushrooms are filled with polyphenols (such as triterpenoids), melanin and superoxide dismutase – antioxidant compounds which help to neutralise free radicals. Antioxidants may also help to reduce low-density lipoprotein (LDL) – otherwise known as bad cholesterol.
- Blood sugar regulation: Chaga may help to improve insulin sensitivity in prediabetics and those with Type 2 diabetes thanks to the fact that it is high in beta-D-glucans. However, it has also been known to dramatically lower blood sugar which can cause hypoglycaemia, so it can be unsafe for Type 1 diabetics taking insulin.
- Anti-cancer properties: According to the Memorial Sloan Kettering Cancer Centre some preclinical studies have demonstrated that chaga showed inhibitory and pro-apoptotic effects against colon, lung and liver cancer cells. Inotodiol, a natural triterpenoid compound found in chaga (Inonotus obliquus) has also exhibited antitumour activity against cervical cancer cells. However, more studies are required to understand the potential anti-cancer benefits of chaga.
The risks of supplementing with chaga mushrooms
- Lowering blood sugar: An excess of beta-D-glucans may cause hypoglycaemia.
- Inhibiting platelet aggregation/clotting: If you are on blood-thinning/ anti-coagulant medications, consult your doctor before taking chaga as it may affect the blood clotting process.
- Renal function: Chaga mushrooms are known to be high in oxalates (oxalic acid), which can bind with minerals like calcium, potentially interfering with their absorption and increasing the risk of kidney stones in some individuals. Those with a history of kidney stones or renal failure should avoid chaga.
Always consult a medical professional before incorporating mushroom supplementation into your routine, especially if you take other daily medications.
