We support accurate labeling of mushroom products

Two major mushroom product makers are at odds over what can be labeled as real mushroom products, and we have thoughts. NAMMEX wants the FDA to regulate the word “mushroom” in products to mean the full mature mushrooms depicted on their labels and in centuries of cultural use. Host Defense’s Paul Stamets wants his lab-grown mycelium to be labeled as the fully grown mushrooms depicted on his labels. As a mushroom extract maker who uses fully grown mature mushrooms, Half Hill Farm supports accurate labeling of mushroom products.

Recently, mushroom product maker NAMMEX filed a regulatory request with the FDA seeking clarity in mushroom supplements industry labeling.

At issue are major brands that make “mushroom” products from lab-grown sheets of mycelium cheaply propagated in a matter of days on rice or grain substrate. Once the substrate is myceliated, it is then dried, and extracted or encapsulated and labeled as made from the mature mushrooms often depicted on the label. These products unfortunately often contain the actual grain substrate in the product and are consumed by the purchaser. Some companies, like Host Defense, accurately include “rice” or “grain” in their ingredients because of this. Some don’t. Either way, the shorter and cheaper process certainly makes for more profit.

It is no surprise that some brands that make products from mycelium are upset with NAMMEX and have issued a statement opposing their effort. One statement, led by Host Defense’s Paul Stamets, argues that his company and other major brands should be able to label their mycelium products as “mushrooms” because mushrooms are made of the mycelium he uses to create his products. You can read his statement here.

At the same time this regulatory request for clarity is being made by a mushroom product maker, the poultry industry, in a bit of irony, won FDA approval allowing them to label lab-grown cultured cells as “chicken.” While science can definitively conclude a petri dish of cultured cells is indeed cultured from real chicken (just as mycologists can determine mycelium is cultured from real mushrooms), a plate of lab-grown cells is not the same as the real thing.

Here at Half Hill Farm, our mushroom extracts use the fully mature mushrooms pictured on our labels that take months to cultivate. Mature mushrooms experience months of growth and controlled conditions to produce the full spectrum of compounds that are extracted. The distinction between mushroom extracts and mycelium extracts set us apart from many major brands and is important to us.

Mushrooms have evolved to survive millions of years of changing conditions to be the oldest living thing on our planet. The result of that evolutionary outcome is eons of wisdom in the form of the full fruited body of the mushroom itself that we should respect and revere with proper labeling.

How to make sauerkraut – fermenting veggies


FERMENTING VEGGIES: This small haul from the Murfreesboro Saturday Market got made into some tasty sauerkrauts we hope will be ready late next month. These are recipes with ginger that we make at home for ourselves and decided to add to the krauts we currently offer at Wellness Emporium – Woodbury. One is Ginger Beet. The other is Carrot, Ginger, and Turmeric.

HOW TO MAKE SAUERKRAUT: Sauerkrauts are easy to make and so good for you. They are rich in dietary fiber, nutrients, andgut-healthy probiotics.

All you need to do is chop up a blend of 75% cabbage with 25% other veggies and 2% salt added. Weigh all your cabbage and mulitply the weight time 0.33. The resulting number is your 25% of other veggies. After chopping or shredding your ingredients, mix them together and weigh it. Multiply the total weight with 0.02. This is how much salt you need to add, which is 2% of the total weight.

Mix all these together kneading the veggies in a bowl. You should see brine dripping from each fist full. Let it sit for about 20 minutes, then place in a fermentation vessel for about three weeks making sure all the veggies are completely submerged in its own brine. You can use fermentation weights to hold your fermenting veggies below the brine surface, or fill ziplock bags with water and place on top.

Fermentation will go through a couple of phases. If you use an airlock or airtight lid, you will need to burp the ferments. This will take about 3 weeks. When it’s done, jar it up and refrigerate to slow or stop fermentation. It should be a crunchy, tangy, probiotic bite of fermented goodness you can add to most meals!

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.
