PRODUCT DESCRIPTION

+

Potent Birch Polypore liquid extract made in England - Powerful, premium quality tincture.

Super Strength - 1:3 Dual Extracted - Fruiting Body Only

The ultimate fusion of nature and science: Fung Shui’s premium mushroom tinctures. We think they are the best due to their high strength 1:3 extraction ratio — using 1 part fruiting body to just 3 parts liquid. This is 25% stronger than a 1:4 ratio and double the strength of a 1:6 ratio. We don't add the mycelium or substrate to ensure we keep the concentration of bioactive compounds as high as possible. 

Our laboratory extraction team insist on this process to ensure the highest potency and bioavailability. It also means that Fung Shui tinctures provide more bang for your buck.

    INGREDIENTS

    +

    Simple: 100% Organic birch polypore (Fomitopsis betulina) fruiting body only (10,000mg), organic triple distilled ethanol, spring water, and that’s it – no additives, flavourings, fillers or preservatives.

    SOURCING

    +

    Our mushrooms are organic, sustainably grown and harvested, with a dedication to purity, provenance and environmental care. We try also forage some of our mushrooms (there are restrictions about which mushrooms can be foraged from the wild).

    HOW TO USE

    +

    Take 3 dropper squeezes (approx 2ml) daily. Mix it into your favourite beverage or food (for hot drinks or food, wait until they have cooled slightly to 70° C or below so as not to destabilise beneficial compounds). Alternatively place it under your tongue. Consistent and long term use amplifies the benefits, as does taking it in between meals or 30 minutes before a meal, ideally with a glass of water. Evidence suggests that vitamin C enhances the bioavailability of polysaccharides and that multiple mushroom strains at the same time may offer synergistic benefits.

    Ancient Wisdom. Modern Science.

    SKIN HEALTH & NATURAL DEFENCES

    Birch Polypore has been traditionally used to support the body's natural ability to maintain healthy skin barriers and immune function, with natural antimicrobial compounds helping protect against everyday challenges.

    CELLULAR HEALTH & RESEARCH

    Birch Polypore has a history of use in maintaining health at a cellular level. Adjunctive oncology research has explored its role in supporting normal immune function and quality of life alongside conventional therapies.

    DIGESTIVE HEALTH & GUT SUPPORT

    Traditionally used to support digestive wellbeing, Birch Polypore is rich in prebiotics, helping to nourish beneficial gut flora and promote a healthy internal environment.

    IMMUNE SUPPORT

    Rich in triterpenes such as betulinic acid, Birch Polypore has been studied for its ability to support natural immune resilience against everyday challenges.

    OXIDATIVE STRESS & DETOXIFICATION

    Birch Polypore contains bioactive compounds and natural antioxidants, traditionally used to support the body's ability to manage oxidative stress and maintain natural detoxification pathways, contributing to overall vitality.

    COGNITIVE HEALTH & PROTECTION

    Birch Polypore contains natural compounds traditionally used to support cognitive function and mental clarity. It helps protect cells from oxidative stress, contributing to the maintenance of normal brain health and resilience.

    • Enhanced Bioavailability

      Tinctures are highly bioavailable (up to 7 times that of powder according to the University of Queensland), so more absorption per dose, boosting effectiveness and cost efficiency.

    • Faster Absorption

      Tinctures are absorbed directly into your bloodstream via sublingual use and through your gut lining when consumed, meaning quicker results than powders and capsules.

    • Easy Squeezy

      No need to swallow capsules or make a mess with powders. Fung Shui tinctures offer effortless administration - either directly under the tongue or combine with food or drink.

    • Gentle On Your Gut

      Bypass the need for stomach acid and enzymes, absorbing directly through sublingual glands or the gut lining. Unlike capsules, they minimise digestive strain, making them ideal for sensitive stomachs.

    • Personal Dosing

      Tailor your precise dose to your unique needs. With a dropper you can adjust the amount you take based on your own personal health goals. You can also mix tinctures which can enhance health benefits.

    • Long Shelf Life

      Our amber glass bottles block UV light, extending the shelf life. If kept below 25C your tincture can last for years. The potency of a tincture does not degrade over time like powders and capsules.

    The Fung Shui Promise

    When it comes to quality, potency, and purity, Fung Shui sets the standard.  We use traditional extraction methods, have a short list of ingredients, and zero additives. This makes our tincture a premium standard. Here’s why our tincture is hands down the best choice:

    Premium 1:3 Ratio For Maximum Potency
    +

    Our 1:3 extraction ratio (e.g 1kg of mushroom per 3 litres of liquid) offers a stronger, more effective tincture than the typical 1:4 or higher dilutions found elsewhere.

    Fruiting Body Only
    +

    Most mushroom supplements are diluted with mycelium on grain. We use 100% fruiting body—the most potent part of the mushroom.

    ✔ Higher Active Compounds – More beta-glucans, triterpenes & antioxidants.
    ✔ No Grain Fillers – Just pure mushroom power, no starch or residue.
    ✔ Tradition Meets Science – Used for centuries, now proven by modern research.
    ✔ Superior Extraction – Dual-extracted for full-spectrum potency.

    Dual Extraction For Full Spectrum Compounds
    +

    By combining alcohol and hot water extraction, we capture both water-soluble and alcohol-soluble compounds, crucial for breaking down the cell walls, This cell wall is composed of chitin, a robust substance also found in the hard shells of crabs, lobsters, and insects. Since the human body cannot digest chitin, an extraction process is essential to release the beneficial compounds from within the cell wall. This ensures you receive the complete spectrum of beneficial compounds, including polysaccharides, beta-glucans and triterpenoids. The alcohol also makes it last longer. We don’t triple extract the mushrooms, because the higher heat (up to 120C) can destabilize the already extracted compounds, so we stick to tried and tested traditional methods to optimise extraction.

    100% Vegan, Non-GMO, And Gluten-Free
    +

    Clean, ethical ingredients without compromise.

    UK Native Species
    +

    All our mushrooms are grown, foraged, made and bottled in good old Blighty – the home of cold, damp conditions perfect for mushroom growing. This also decreases the food miles created in the supply chain.

    High Quality Alcohol
    +

    Triple distilled and organic alcohol is one of the reasons why our tinctures taste so smooth, and so they should given the short ingredients list.

    No Additives, Flavourings Or Preservatives
    +

    We want to be true to the immense power of mushrooms, so don’t add, you guessed it…..any flavourings, additives or preservatives whatsoever. No need to be concerned about additives which can be found in powders and capsules, or bulking agents or preservatives for that matter. We don’t add anything during the extraction process other than the dried fruiting body, spring water and triple distilled alcohol. Nice.

    Organic Mushrooms Only
    +

    When not foraged, we only source organic mushrooms from our UK farmers.

    absolutely love this product.

    i’m aware birch is helpful for your immune health, but i didn’t know expect the results i have had. since taking birch i’ve not been ill at all, and i just overall feel a lot healthier in myself. i used to have gut issues post travelling and i believe it was linked to microbial issues in my gut. since taking the birch alongside the other mushrooms my gut health has improved substantially! i swear by this product especially if you are often prone to illness, allergies, feel like your immune system could do with a boost, but also for gut health too!

    Birch polypore

    Bought this as I'd heard good things for various benefits I'm in need of. Arrived quickly but tastes too strong to put under my tongue, so I now just add to my drink and I can't taste it.

    THERE'S NO SUCH THING AS A SILLY QUESTION:

    WHAT DOES IT TASTE LIKE?

    +

    We are really proud to use a traditional extraction process and keep the ingredients
    list really simple. When added to a food or drink we can’t decipher any taste at all, when taken neat, one might expect an earthy, strong mushroom taste but in reality it’s surprisingly fairly mild and smooth – perfect for people who don’t like mushrooms but don’t want to miss out on the benefits.

    IS IT SAFE TO USE YOUR MUSHROOM PRODUCTS ALONGSIDE MEDICATION?

    +

    Yes, our 100% organic and natural mushroom tinctures should be totally safe
    with medications, however, it’s best to check with your healthcare advisor
    before use if you have a pre existing medical condition.

    HOW LONG UNTIL I FEEL THE EFFECTS?

    +

    We have some customers reporting positive benefits on day 1, especially with Lion’s Mane and Reishi with regards to improvements in sleep, however each person and their routine is different, so it’s impossible to say definitively. We recommend using the tinctures for a month and journalling your journey with the key parameters that are important to you, perhaps with a score out of 10, so you can begin to plot the extent of an improvement timeline in the areas in need of help, specific to you. Please do share your results with us by leaving a review.

    CAN I TAKE DIFFERENT MUSHROOM TINCTURES AT THE SAME TIME?

    +

    Absolutely – it’s perfectly safe to do so and indeed can exacerbate the benefits. It’ll
    be harder to analyse which mushroom is helping with which symptom or improvement needed, but if you’re feeling the benefits, that’s the most important thing.

    IT CONTAINS ALCOHOL – CAN I STILL DRIVE AND WORK?

    +

    Don’t worry, the alcohol won't test positive on a test and nor will you feel it’s effects. A daily dose is equal to 2ml, there is approximately 0.5ml of alcohol in one serving. This is the equivalent of drinking 4ml of a standard glass of 12.5%vol glass of wine or just 10ml of a 5%vol beer. This is such a small quantity of alcohol so you would feel no effects of intoxication. Alcohol is used to extract the alcohol soluble compounds so they are bioavailable for the consumer. Without using alcohol in our extraction process, there would only have the water-soluble compounds and not the full spectrum. The alcohol also increases the shelf life.

    HOW SHOULD I STORE FUNG SHUI TINCTURES TO BEST PRESERVE THEM?

    +

    We suggest keeping your mushroom tinctures in a cool, dark place, out of direct sunlight. A kitchen or bathroom cupboard would do nicely.

    I'M ALLERGIC TO MUSHROOMS, CAN I CONSUME FUNCTIONAL MUSHROOM TINCTURES?

    +

    We wouldn't recommend that you do. Should you require advice about your allergy please consult your healthcare advisor.

    CAN I USE FUNG SHUI TINCTURES LONG TERM?

    +

    Yes. In fact the best results are achieved when used consistently over time. As adaptogens, they work steadily to enhance the body’s natural ability to manage stress and maintain balance. You may notice benefits within a few minutes, hours or days or a even a few weeks.

    ARE THERE ANY SIDE EFFECTS OR SAFETY CONCERNS?

    +

    Functional mushrooms have been used safely for thousands of years. Allergic reactions or side effects are rare, however they can occur so it's best to check with your healthcare advisor.

    HAVE YOU HAD YOUR TINCTURES TESTED?

    +

    All our mushrooms have a certificate of analysis to ensure they comply with physical & chemical standards. Heavy metals and microbiological testing is undertaken to ensure safety. We are currently undergoing a review with Foodtest laboratories in the UK, a UKAS accredited organisation to test for the beneficial compounds in our products as well as to ascertain the extent of neural growth performance. With so many benefits of mushrooms to body and brain, the prohibitive costs of testing each benefit means it will take time and money, but watch this space, we are dedicated to the cause - as the results come in, we will post them in our research section.

    ARE TINCTURES MORE POTENT THAN POWDERS?

    +

    The potency of any mushroom supplement depends on the amount of mushroom present in the supplement. We pack as much mushroom as possible in our products. Tinctures allow for a much more efficient and effective absorbtion into your system (up to 7 times according to a University of Queensland study) of the desired mushroom, thus making them much more potent.
