Lion’s Mane mushroom extract improves brain cell growth

A new study in the January 2023 Journal of Neurochemistry shows unique compounds in Lion’s Mane mushroom extract boost memory by boosting nerve growth.

The study identified two bioactive compounds, N-de phenylethyl isohericerin and Hericene A, that appear to regulate the growth of neurons that improve memory.

The extracts had a “clear neurotrophic effect,” they write, resulting in doubly long axons – the threadlike links that conduct impulses away from a neuron – and more than triple the number of neurites, or small projections from a neuron that can grow into fully functional axons or dendrites.

“Laboratory tests measured the neurotrophic effects of compounds isolated from Hericium erinaceus on cultured brain cells, and surprisingly we found that the active compounds promote neuron projections, extending and connecting to other neurons,” Meunier says.

Researchers describe the compounds present in Lion’s Mane mushrooms as potent memory enhancers that may provide hope for natural memory enhancement for an aging population. Read more from University of Queensland researchers.

What customers are saying about our mushroom extracts


Half Hill Farm’s mushroom extracts – available online and our retail store in Woodbury, TN

When it comes to using natural remedies alone, or as adjunct therapies in the treatment of disease, no two people will have the exact same result. Customer feedback from the past three years, however, has shown us patterns of success that are making a difference in their health and well being.

While we are not doctors and cannot make any claims that our products can diagnose, treat, cure or prevent any disease, we are proud to hear a growing number of customers come from doctor recommendations. Our mushroom extraction process was first formulated for a family member to match standardized processes used by scientists and ethnobotanists for the purposes of many clinical trials and studies because we were not happy with the quality available in the market. The recognition of our quality and reports of better health and well being are humbling and give purpose to our work. It’s also as close to an authentic voice our products can have on behalf of what they can do for others.

Patterns of success: The general experience shared by our customers is that doctors are amazed at better than expected results (These customers didn’t experience the hair loss, appetite loss or nausea typically associated with primary care options and often seen in patients around them, and their blood work often surprises doctors showing strong immune response where a dramatic drop was expected). These observations match the results of recent U.S. based clinical trials. Customers with the most success take 2-3 times the daily serving of our extracts during treatment for various cancers followed by regular daily servings as maintenance. Requesting integrative care options early in cancer treatment exposed customers to alternative treatment options that include mushroom extracts. Examples of integrative care programs can be found at M.D. Anderson Cancer Center and Memorial Sloan Kettering Cancer Center. One of the most common patterns with these customers is a change in diet that adds more juicing and less meats as well as adding turmeric and black pepper seed oil (piperine in the black pepper dramatically increases the bioavailability of curcumin in turmeric to reduce inflammation).

Feedback: Below are excerpts of written feedback in letters, cards and emails from some of our verified customers who have agreed to let us share their experiences. We have slightly anonymized the names of customers below, but if you have questions or more testimony to share, add them in comments.

My mother has stage 4 Lung and brain cancer. She was given 6 months to live and we just passed year 2. She is on a maintenance chemo and in addition to her vitamin regiment I think your product is helping save her life. Thank you! ~ S.O. in Minnesota

I purchase your extract for our son who has been diagnosed with stage 4 colon cancer. He has had surgery and had 12 rounds of chemo with no avail. He is now on his second round of chemo for eight treatments. He has been taking the turkey tail extract (a friend recommended it and you) for four weeks today and he feels so much better! His appetite is back and his numbers have been “phenomenal”! He will be having a CT Scan the beginning of December and we are hoping it shows his tumors being affected (we are actually hoping for a “miracle” and it be gone). He is surprised at the amount of energy he has now that he is taking your product. He is taking 2 teaspoons in a cup of tea every morning. I pray everyday this is our answer. Our son says he will take it the rest of his life if it works! Thank you for your dedication to the health of your fellow mankind – it truly gives us hope! ~ J.P. in Wisconsin

This isn’t about money. It’s about who does things right and won’t cut corners and that’s why i believe your products are the finest offered anywhere. This product is Awesome. I’m 72 and have more energy than I ever had. ~ H.M. in Florida

Last report was from the radiologist who was excited to see small changes. Couldn’t explain it. This week we saw his oncologist who was very pleased with the progress & admitted there was definitely some changes going on. With that he added, “Don’t stop what you’re doing.” This is huge!! His Dr. encouraged him!! His oncologist really doesn’t want to know about what the “new” changes are that he is doing but his Dr. saw improvement!! Thank you for all of your blood, sweat & tears.  Thank you for taking risks & stepping out and working so hard for a vision that you believe in. You are changing lives & giving hope where there has only been hopelessness. ~ J.D. in Virginia

I just started taking turkey tail liquid over a month ago. I have stage 4 breast cancer and I went for my monthly shots and exams. My tumors are shrinking and my labs have changed for the better tremendously. My Dr. Was shocked and did not start me on another chemo pill that she intended to do that visit. God has blessed me with this. And I will continue to take it. Thank you so much. More time with my children. ~ K.I. in Kentucky

I was diagnosed in May 2016 with a tick-borne disease. (Not Lyme, but a similar type of disease with similar symptoms.) The aftermath of these diseases can last for months if not years! As part of my treatment, I took Turkey Tail Mushrooms. Within 3 weeks of starting to take them, I was completely better. My doctor could not believe it, and said that all the blood work indicated that the disease was gone. The biggest problem with those diseases is inflammation and auto-immune response. I really believe the Turkey Tail was the factor that made the difference! Definitely take it in your coffee, it took a couple days to get used to it, but it kind of tastes like vanilla, so was easy to get used to! ~ K.F. in Tennessee

‘You saved my daughter’s life!’ – the healing power of mushrooms


A ‘cloud’ of Turkey Tail mushrooms (Trametes Versicolor) on logs at Half Hill Farm

A few months ago, I got a call from a customer who was looking for what I thought was an adjunct therapy for his daughter in treatment for brain cancer. His own research made him hopeful that our Turkey Tail extract could help. It wasn’t until a couple months later that I discovered on a second call the full extent of what was going on.

“I want you to know you saved my daughter’s life,” the customer told me. It’s something I hear often from customers, from ecstatic calls of people now in remission to those experiencing little to no side effects to chemo or radiation (most common) and positive changes in blood tests, but when he told me his daughter had been in hospice, I was shocked.

It is certainly not a common experience for patients to go from hospice back to treatment options, but it’s stories like this that give what we do meaning and purpose. It’s stories like this that are why we have grown into an FDA-registered manufacturing space and why we continue to expand our product offerings to include nature’s very best organically grown and wildcrafted mushroom extracts.

We are humbled every day with your phone calls and emails. While the body of research on mushrooms is growing, we know we cannot market our extracts or products as a treatment, cure or prevention of any disease, but that doesn’t stop our customers from sharing their stories. It has presented a unique challenge over the past two years as to how we present those stories to you in a responsible way.

Mushroom Dual Extracts available in 100 ml (3.38 oz) or 200 ml (6.76 oz) bottles from Half Hill Farm:

If you are one of the hundreds of customers across the country who take our extracts, we would love to hear why you take them and what you are experiencing. Your experience could help someone follow you on a path toward better health and well-being. You can leave your comment here, or leave a review on the product pages of our online store.
