Can Lion’s Mane Treat Diabetes?


Lion’s Mane is typically known as a Nootropic herb. But Lion’s Mane may also have the potential to treat diabetes.

How Does NGF Effect Diabetes?

Lion's Mane Mushroom white pearl color in the shape of a 7 inch long thick beardLion’s Mane has a chemical called Hericenones, which promotes Nerve Growth Factor (NGF) in the body. As the name suggests, NGF is responsible for the growth and survival of nerve cells, or neurons. NGF affects the neurons in the brain, but NGF is also related many different biological processes, not just brain function.

For example, NGF is also involved with the regulation of the immune system and survival of pancreatic beta (β) cells.

An NIH study[1] indicates that pancreatic β cells naturally secrete NGF , and require NGF for survival. When pancreatic β cells no longer receive NGF, they undergo cell death and are less likely to survive.

A decrease in the number of insulin producing beta cells in the pancreas is what leads to diabetes. So perhaps a decrease in NGF needed by the beta (β) cells in order to survive, may also contribute to diabetes. So the question is, what prevents beta cells from receiving adequate NGF?

Well, I speculate that chronic stress, depression, and obesity all lower the levels of NGF in the body. And it so happens to be that chronic stress[2], depression[3], and obesity also increases the risk for diabetes.

But as I dug deeper, I found that both acute (high short-term) and chronic stress increases the levels of NGF in the body, as an adaptive mechanism to stress[4]. So why would chronic stress be a risk factor for diabetes?

Depression contributes to chronic stress, so the same question can be asked if depression as a risk factor to diabetes.

And obesity, except for the extreme cases, also increases the amount of NGF in the body[5]. But again- obesity is a risk factor for diabetes.

What Causes Diabetes?

After further research, I have found that the reason why chronic stress, depression, and obesity are risk factors for diabetes- is because they all contribute to low level but chronic inflammation in the body. Chronic inflammation is a slow killer.

Inflammation is Like being set on fire…

Overtime, chronic inflammation causes the cells in the body to be damaged by oxidative stress, especially the more delicate structures like the DNA. And do you know what happens when a cell’s DNA is damaged?

When a cell’s DNA is damaged, most of the time the cells undergoes apoptosis, or cell death in order to prevent harmful mutations from spreading. So cells that regenerate in the body at a slower pace cannot keep up to replace the cells that have died before. That includes the pancreas- so you end up with not enough beta cells to make insulin. That is one way for diabetes to appear.

And you know, wound healing in diabetic patients is very slow. That is no coincidence.

Delayed wound healing indicates that the body is having a harder time regenerating itself. The cells aren’t dividing fast enough to quickly heal the wound. We already know that chronic inflammation can prematurely kill cells off. What else can contribute to delayed wound healing in diabetes?

Well according to an NIH study, many things:

Factors such as age, obesity, malnutrition, and macrovascular and microvascular disease may contribute to wound infection and delayed wound healing especially in the type II diabetic patient. In addition, hyperglycemia caused by decreased insulin availability and increased resistance to insulin can affect the cellular response to tissue injury.[6]

According to the study, many different factors contribute to delayed wound healing. On top of that, diabetes also contribute to delayed wound healing by causing hyperglycemia (too much blood glucose) due to a lack of insulin (a.k.a diabetes).

So what causes delayed wound healing also may contribute to beta cells not being able to regenerate fast enough to replace the dead ones and prevent diabetes. So what can? …Does Lion’s mane have a place in treating diabetes?

How Lion’s Mane Can Help Diabetes

We already know that Lion’s Mane can increase the level of NGF in the body. But mild obesity and stress also can cause NGF to increase. I suppose you can say that since an increase in NGF is the body’s adaptive mechanism towards a stressor, Lion’s Mane in theory helps the body adapt. So what else can Lion’s Mane do?

Lion’s Mane also reduces inflammation[7]. We already established that stress and obesity may cause chronic inflammation. And that chronic inflammation may contribute to diabetes. So by treating the chronic inflammation, we are in theory taking away a risk factor for diabetes.

The methanol extract of H. erinaceus was concentrated to remove solvent yielding a residue (referred to as HEM) which was added to the diet. The hypoglycemic effects of feeding HEM to streptozotocin-induced diabetic rats were studied. Polydipsia was stronger in induced diabetic rats not fed HEM than in those receiving HEM. Rats fed with HEM had significantly lower elevation rates of blood glucose level than those not fed with HEM.[8]

In this particular study, rats were given streptozotocin to induce diabetes- streptozotocin is a chemical that is toxic to the insulin producing beta cells in the pancreas.

The study prepared 3 different groups of rats: those that were “given” diabetes & the Lion’s Mane treatment, those with “given” diabetes without Lion’s Mane, and lastly a control group of rats without either.

What the study found was that the Lion’s Mane reduced Polydipsia (abnormally great thirst, which is a symptom of diabetes) in the diabetic rats as well as lowering blood glucose levels. This is relevant because the treatment of diabetes involves the use of medications to control blood glucose levels from becoming too high. The typical medications used to treat diabetes often come with undesirable side-effects. So with enough supporting research, Lion’s Mane could be offered to doctors as an alternative treatment for diabetes.

  1. five months ago I constantly had to go to the bathroom. I thought it was because I gave up soft drinks and was only drinking water. One day I had a stomachache. I was in bed for 4 days. The doctor’s appointment was for a Wednesday. I got sick and went to emergency room on a Monday. I was told my blood sugar level was 810 and I have diabetes. Since then, As the disease progressed all medication stopped working, i was introduced to Health herbal clinic in Johannesburg who have successful herbal treatment to diabetes . I spoke to few people who used the treatment here in USA and they all gave a positive response, so i immediately purchased the diabetes herbal remedy and commenced usage, i used the herbal supplement for only 7 weeks, all symptoms gradually faded away, herbs are truly gift from God. contact this herbal clinic via their email healthherbalclinic @ gmail. com or visit www. healthherbalclinic. weebly. com
