Red Reishi extract reverses obesity by altering gut bacteria

A new study of liquid dual extracts of Red Reishi mushrooms (Ganoderma Lucidum) published this Summer shows a reversal of obesity related symptoms by altering the balance of good and bad gut bacteria.

“Mice kept on a high-fat diet gained up to 25 percent more than mice kept on the same diet with extracts from the Reishi mushroom,” said David Ojcius, a microbiologist at the University of the Pacific School of Dentistry in San Francisco who participated in the study, published Tuesday in the journal Nature Communications. Consumption of Reishi mushroom extract with high-fat food prevented the development of fat tissue, gut inflammation and buildup of harmful bacteria in the bloodstream — all symptoms of obesity in both mice and humans.

The study also shows an adaptogenic effect, meaning the liquid mushroom extracts slimmed down overweight mice only, not mice with healthy weights. Prebiotic uses of this medicinal fungi builds on research that increasingly points to a balance of gut bacteria addressing overall health and well-being, including obesity.

An early hint that gut microbes might play a role in obesity came from studies comparing intestinal bacteria in obese and lean individuals. In studies of twins who were both lean or both obese, researchers found that the gut community in lean people was like a rain forest brimming with many species but that the community in obese people was less diverse—more like a nutrient-overloaded pond where relatively few species dominate.

Nature’s Remedy: Half Hill Farm has created a high quality Red Reishi dual extract using USDA certified organic ganoderma lucidum, USDA certified organic USP pharmaceutical-grade alcohol and distilled water. You can purchase our Red Reishi Mushroom Dual Extract in 100 ml (3.38 oz.) or 200 ml (6.76 oz.) bottles.

UPDATE: mushroom workshop pavilion progress

Construction started this week on Half Hill Farm’s mushroom workshop pavilion. Made of locally milled oak & cedar, it’s a perfect setting to help foster an important relationship with nature through a hands-on learning experience. We can’t wait to share this beautiful space with you this Fall here in rural Woodbury, TN!

We could not have done this without you! Back in March of last year, several of you helped us raise a portion of the funds we needed to build this shelter. We didn’t meet our goal, but with a little hard work and support we are finally creating a space to share sustainable fungi-culture & our love of the outdoors.

We are also humbled by the love and appreciation for the healing products we create out of personal needs and our deep reverence for the natural world. Our 1:1 Red Reishi mushroom dual extract was first introduced as a gift to donors of this project last year and has since shipped to over 40 states to folks seeking nature’s balanced remedy. There is never a day we are not here quietly listening, learning and creating. Every day you reach out to us and share your story of why and how you found us affirms our commitment to serve.

Getting the most from your Shiitake mushroom log

Shiitake mushroom logs in the woods at half Hill Farm

Last night looks like the last of forecasted freezing temperatures for early Spring here in Middle Tennessee. If you have one of our Shiitake mushroom logs marked SP15 (Spring 2015) or earlier, now is the time to prep your log for an early Spring flush.

Shocking logs: Get a five gallon bucket and fill it with rain water or water from a nearby creek and then soak your log for 24 hours. Place the log in a wooded area with roughly 80% shade. You can place it under a bush near your house’s North side if you do not have woods. If you have more than one log, use a larger tub like the one pictured above. The water should not be chlorinated tap water and should be very cold. This hard soak and cold temperature followed by the gradual warming of outdoor Spring temps will “shock” the mycelium into “pinning,” the beginning stages of mushrooms.

Pinning: Each pin that forms pushes through the bark as you see pictured above and will develop into the beginnings of a mushroom within 2-3 days followed by a rapidly growing mushroom over a five day period. Depending on the weather throughout Spring, you could experience 2-3 natural cycles of mushrooms with roughly two week resting periods between each flush.

Harvest: Once you start to see the mushrooms unfurl their outer edge (typically tucked under the mushroom cap), it is time to pick mushrooms. At this point, the mushroom is in the early phase of releasing its spore. Simply cut them off at the log, brush off any debris and either eat them fresh, store them in the fridge for up to two weeks, or dry them to use for months to come.

How to purchase: Each Shiitake mushroom log from Half Hill Farm produces up to 90% of the log’s dry weight in mushrooms over a 3-5 year period. You can purchase your own inoculated logs from 15 lbs. one foot logs up to 50+ lbs. four feet logs at our farm here in Woodbury, TN. Just give us a call and let us know you’re coming!

Spring planting 2015: seeds of change and progress

Spring is about 6 or 7 weeks away. Time to get the popup greenhouses out and get these seeds going!

Progress: Last March, many of you helped us raise funds to open our farm to more mushroom workshops. Although we fell short of our goal, a little hard work made up the difference. Thanks to your help, the workshop pavilion pad is getting poured next week (somewhere in the photo above) along with the entrance to our farm! We’re excited about what this means for accommodating growing interest in our certified organic mushroom production and farm practices.

This year is our official harvest of Tennessee’s first certified organic crop of hops on our farm! Most of this year’s harvest will be dedicated to a new product coming out this Fall with some hops available to local brew clubs. Follow us on Facebook to know when these items will be available.

Change: This year we will not be regular vendors at the Woodbury Farmers’ Market due to demand for our mushroom products. We’re still figuring out what days we’ll be there. This year will be our first official apple and blueberry harvest, and we’re excited to make these available through local restaurants or at our local market.

Seeds: We’re planting a lot of our favorites for salsa making this year from newly purchased certified organic seeds. Like our Shiitake mushrooms, whatever vegetable produce doesn’t turn into Raw Salsa will be available direct to local restaurants.

RECIPE: Shiitake mushroom soup

Once your Shiitake logs from Half Hill Farm start producing mushrooms, you can dry them, store some in the fridge for a couple weeks, or eat them! That’s exactly what we did using the following recipe and an unexpected January harvest.

There’s a lot you can do with your Shiitake mushrooms and a lot of good stuff it will do for you. One recent study, for example, shows medicinal compounds in Shiitake mushrooms can eradicate HPV, a virus that causes 99% of all cervical cancer, 95% of anal cancer, 60% of oropharyngeal cancer, 65% of vaginal cancer, 50% of vulvar cancer, and 35% of penile cancer. Here’s more research on this and other mushrooms we grow, and here’s our recipe for how to make some Pho-tastic Shiitake mushroom soup.

Shiitake Mushroom Soup

  • 2 cups chopped Shiitake mushrooms
  • cubed tofu
  • 4 cloves of garlic
  • 4 tbsps of fresh grated ginger
  • chives
  • cilantro
  • 4 cups chopped Napa cabbage
  • rice noodles (or rice & quinoa)
  • 8 cups of chicken or vegetable broth
  • soy sauce (or Bragg’s) & lemon to flavor

You can use either rice noodles or a little rice and quinoa. Either way, cook these first and set them aside. You won’t need much – about a total of half a cup if using rice/quinoa.

Put a little olive oil in the soup pot you plan to use and cook your cubed tofu. When complete, stir-fry the chopped garlic cloves and ginger with the cooked tofu. This takes a couple minutes. Now add the broth, mushrooms and either noodles or rice/quinoa. Let this simmer for 20 minutes and then add the Napa cabbage and let simmer for five more minutes before serving.

Place a little chopped cilantro and chives in a bowl and fill the bowl with soup. Add a generous squirt of soy sauce or Bragg’s and a squeeze of a couple lemon wedges and enjoy!

The sum of this year’s goodness


Our friends at Yellowbird Farms take a break from sheep to make Shiitake mushroom logs.

Our first season of mushroom log workshops is now closed as we head into the Winter thankful for another amazing year!

The 20 mushroom workshops we did this Fall on our farm helped introduce several people in our community to a sustainable way to grow edible Shiitake mushrooms. We are grateful to our neighbors who offered us their fallen or storm damaged oak trees for mushroom production. The logs we used helped sequester over a ton of carbon back into our food chain rather than being released back into the atmosphere as fire wood.

We were also excited to begin offering mushroom logs at our local farmers’ market in Woodbury this Summer and look forward to expanding these health & educational opportunities next year.

Despite a personal loss in our family with the passing of Sandra Landers, we were inspired to create Red Reishi and Turkey Tail extracts that now help others and fullfill our mission to be good stewards of our planet and our general well being. We are so grateful to those who seek us out and who continue to enhance our understanding of how our extracts are used.

The sum of the year’s goodness ultimately comes down to each of you. By taking a personal step to buy local, buy organic and support a sustainable lifestyle, your combined action has become the change we want to see in the world. We are forever grateful to see that at the end of a long season. Thank you for that!

Turn your storm damaged trees into mushrooms


This lightning struck White Oak became several Shiitake mushroom logs.

It’s always fortunate when the only damage from a storm is to property. Sometimes that includes damage to favorite old trees that in a matter of hours is reduced to firewood.

If you had a White Oak, Red Oak, Hickory or Sweet Gum tree that recently fell victim to storm damage, we can help you cut it up and remove as much as we can safely. We aren’t a professional tree service, but we can work with a tree service of your choice or cut up 4 inch or greater diameter logs they leave for us. In exchange for the logs we take, we will bring you a few of the logs inoculated with edible gourmet Shiitake mushrooms.

The inoculated logs will grow 90% of their dry weight in mushrooms over the next 3-5 years and keep decades of sequestered carbon in their tissue from re-entering the atmosphere as burned fire wood. You basically get some logs removed, create a healthy super food source (like this amazing bowl of soup) for your family and help address climate change. It’s a win-win-win!

If you want to turn your storm damaged tree into mushrooms anywhere within an hour from Woodbury or Murfreesboro, TN, give us a call at 615-469-7778.

How to get more vitamin D from your Shiitake mushroom harvest

If you purchased a Shiitake mushroom log from Half Hill Farm that is tagged “F14,” now is the time to follow your soaking / shocking steps to get your first edible mushrooms within a week.

Once your Shiitake mushroom log starts producing mushrooms, there’s a simple technique that dramatically increases their vitamin D before you either eat them or dehydrate them for long term storage.

Mycologist Paul Stamets details this simple process and science here, but the basic steps are pretty simple:

  1. Remove stems and slice into roughly half inch slices.
  2. Spread slices evenly on drying racks (anything that allows air flow) in the sunshine with the gills facing up for 6 peak hours avoiding early morning dew and evening moisture.
  3. Bring the mushrooms indoors overnight to avoid humidity, then repeat 6 hours of sun exposure the next day to achieve 12 total peak hours of UV exposure.
  4. Finish completely drying your Shiitake mushrooms in a dehydrator, and store them in sealed jars. To enjoy anytime, simply soak them for an hour and follow most any recipe for fresh mushrooms.

According to Stamets, Shiitake mushrooms that are not exposed to sun may have less than 40 IU/100g of vitamin D. With the steps above, you can expect 46,000 IU/100g of vitamin D, D2, D3, and D4!

To achieve healthy serum levels of vitamin D exclusively from your dried Shiitake mushrooms, you will need to eat no more than 10 grams a day which is roughly equivalent to 100 grams of fresh Shiitake (3.6 ounces).

Purchase your own mushroom log: Our one foot Shiitake mushroom logs are available for scheduled pick up on our farm in Woodbury, TN. They are $22 and will produce 15-20 lbs. of mushrooms over a 3-5 year period. Here is how to get yours.

Make your own mushroom log: Schedule your own private 2-3 hour mushroom log workshop for groups of up to four people on our farm, take home the log you make, and start turning your own logs into a sustainable food source. Here’s how to schedule your workshop.

Local farm makes medicinal extracts from native mushrooms


Farmers turn to cancer-fighting – Cannon Courier – April 9, 2014

(WOODBURY, TN) Mushrooms are revered in ancient herbal medicine as a cure-all for everything from colds and flu to cancer. With recent research validating some of this ancient wisdom, a local organic farm is turning native Turkey Tail mushrooms into medicinal extracts.

Half Hill Farm is a small seven acre USDA Certified Organic farm in Woodbury, TN specializing in apples, blueberries, hops and mushrooms. But a recent cancer diagnosis for one of the owner’s 72 year old mother made mushrooms a priority.

“Cancer has a way of making you change your priorities and rethink your life routines,” said farm co-owner Vince Oropesa. Last year his mother was diagnosed with stage IV lung cancer. Working with her doctors in Murfreesboro, he began providing her with extracts from a native Turkey Tail mushroom as an adjunct therapy to chemo treatments.

“She was at a stage in her health and age where the doctors left it to her whether to go through chemo,” Oropesa said. “We take it a day at a time, but she has surprised us and the doctors through every turn. She’s a real fighter.”

Months before the cancer diagnosis, Oropesa and his husband Christian Grantham began building farm infrastructure to cultivate edible mushrooms for local markets.

“When we got the news of Sandy’s diagnosis, our priorities shifted as well to research on medicinal mushrooms growing in our own back yard,” Grantham said.

What the farmers found opened their eyes to an opportunity to not only help Vince’s mother, but also many people dealing with cancer and other illnesses.

“It was a real wake up call to pay attention to what was literally growing right under our noses,” Grantham added. “Life has a way of doing that, and it’s up to us how we respond to that opportunity.”

Turkey Tail (Trametes Versicolor) grows wild throughout Tennessee and the world. The anti-cancer properties of extracted polysaccharides (PSK) and polypeptides (PSP) from Turkey Tail mushrooms are approved cancer drugs in Japan. Private research in America has been limited because pharmaceutical companies cannot patent the results. That has prompted the U.S. government to start funding research.

In late 2012, the Food and Drug Administration (FDA) approved a $5.4 million grant to study 4-6 gram daily doses of Turkey Tail mushroom extract on stage IV colon and lung cancer. This comes on the heels of promising National Institute of Health (NIH) research on breast cancer. The funding also follows a University of Pennsylvania study showing Turkey Tail mushroom extracts dramatically increases life expectancy for pets with cancer.

“The NIH studies alone showing enhanced Natural Killer (NK) cells and reduced tumor growth in breast cancer patients was enough for us to immediately start Vince’s mother on Turkey Tails,” Grantham said.

Since creating their mushroom extracts, Oropesa and Grantham find interest mostly from people whose illness has them searching for natural alternatives and adjunct therapies. The two say the extracts they are creating on their farm are just as effective as preventative treatment.

“We take our extracts everyday,” Grantham said. “We do Turkey Tail in our morning coffee and Reishi in our evening tea. We’re not doctors, so we try not to talk about how we feel because we don’t want to sound crazy, but it is turning into a life-long routine for us.”

The dual extraction process subjects dried mushrooms to a lengthy hot water and alcohol extraction process that takes a month to complete. The result is a 1:1 concentrated dual extract you can mix into foods or drink.

Most of the farm’s customers for extracts are people whose priorities have changed due to illness. To bring their medicinal extracts to a larger market, the two farmers are taking a page from the medicinal marijuana industry and are infusing their product in food.


Red Reishi Mushroom 1:1 dual extract – available as gifts and soon as infused chocolates from our farm’s online store.

“Most people who aren’t sick don’t quiet understand what to do with our extracts, and that’s OK,” Oropesa said. “But everybody understands chocolate, and most eat them before we have a chance to tell them how good it is for them.”

Half Hill Farm offers Spring and Fall workshops on growing your own edible and medicinal mushrooms on oak logs as well as how to make your own extracts. Their mushroom extracts and infused chocolates will be available online soon.
