Don’t Just Take Our Word For It
Got Questions? We’ve Got You.
Everything you’ve been wondering, answered in one place.
Are your mushrooms psychedelic?
Nope — no tripping here. We use only functional mushrooms like Lion’s Mane, Cordyceps, Chaga, Turkey Tail, and Reishi — completely legal, safe, and trusted for centuries to support focus, energy, gut health, and calm. No psilocybin, no mind-altering effects.
Will I feel weird after drinking Mushrooms?
Not at all. You’ll feel focused, steady, calm — not wired, not jittery, not foggy. Mush Mush helps your body and mind find balance naturally, without any "out of control" feelings.
What do your mushrooms taste like?
Our pure mushroom extracts have a smooth, earthy, tea-like flavour — never harsh, funky, or muddy. They blend cleanly into hot water, coffee, smoothies, or recipes without the gritty weirdness. For something even more delicious, we also craft mushroom-infused coffee, cacao, and chai blends — all designed by Melbourne baristas to taste as good as they make you feel.
Are Mush Mush products safe?
Absolutely. We source our mushrooms from pristine, natural environments — like wild Chaga from Siberian birch forests and Reishi from the mountainous Dabie region — and every batch is third-party tested for purity, potency, and safety. No fillers, no grains, no junk — just real, functional mushrooms you can trust. If you have allergies, a medical condition, or are taking medication, we always recommend speaking with your GP or healthcare professional before introducing Mush Mush to your routine.
Can I have Mush Mush every day?
You should! Functional mushrooms work best when you use them daily. They’re non-addictive, safe for long-term support, and designed to help your body adapt to stress, boost focus, strengthen immunity, and more over time.
What if I don’t feel anything right away?
Some benefits, like calm focus or clean energy, can be felt quickly (thanks Cordyceps and Lion’s Mane!). Others, like gut health, resilience, and long-term immune support, build up with consistent use — kind of like a slow-burn upgrade for your whole system.

The Mush Mush Effect
-
Regulated sleep cycle
A uniquely potent, natural sleeping solution. Reishi spore oil is highly prized for its profound effects in promoting regulated, quality sleep. Extracted from the spores of red Reishi mushrooms, this oil is densely concentrated with triterpenes—compounds known for their therapeutic effects, including lowering cortisol levels and boosting REM sleep. Fall more easily into a deep, restorative sleep.
-
Stress relief
Stress LESS! Reishi spore oil contains the highest concentration of triterpenoids available on the market. These compounds are known for their profound adaptogenic properties, which enhance the body's ability to manage and resist physical and mental stressors. Triterpenoids also help to balance the body’s hormonal responses to stress, reducing feelings of anxiety and restlessness.
-
Deep relaxation
Another reason to love Reishi spore oil is its ability to induce deep relaxation, making it an exceptional choice for those seeking tranquility and chilled vibes. The oil is rich in bioactive compounds including peptides and Ganoderic acid, which both possess potent calming properties and act on the central nervous system to promote a state of deep relaxation. Let the tension melt away.
How to shroom

Apply 5-10 drops under the tongue and enjoy
This stuff is amazing!
After just two weeks my sleep quality has improved immensely, I feel energised and refreshed when I get up in the morning and for the first time in a long time my mood and energy levels are actually balanced throughout the day. I honestly feel like a new person! I can't recommend this highly enough to everyone.

Worth every cent!
I generally don’t sleep as much as I should and have a lot of social anxiety. I take this before bed and I sleep like never before. I’m also dreaming a lot more. Whenever I have a big social event I’ll take it beforehand too and it really calms me down ^^

I stop with Melatonin!
I have struggled to fall asleep for years. From blue-light blocking glasses, to sleep sprays on my pillow, to cabbage tea, I've tried almost all the commercial AND home remedies for falling asleep. NONE of them worked as well as Reishi Oil did! I have such a deep sleep and have stopped waking up during the night. I dont even take my prescribed Melatonin Tablets anymore! Thank you MushMush!!

I've recommended it to everyone!
I've been using Harmonious Reishi Spore Oil for a few months now (onto my third bottle and about to order another!). I have a chronic illness that has made me virtually bedbound, and the spore oil has helped tremendously with my sleep and pain. I take it before bed, and if I wake up in the middle of the night, I'll take a few more drops, and it helps get me back to sleep.

Feeling Zen!
