Ivywood is the Irish distributor of MycoNutri medicinal mushroom extracts, supplying customers and healthcare practitioners throughout Ireland. MycoNutri™ Zhu Ling (Polyporus umbellatus) is available from Ivywood in both capsules and powder.
The current MycoNutri™ Zhu Ling formulation is produced from cultivated Polyporus umbellatus sclerotia and combines 50% high-concentration hot-water extract (8-10:1) with 50% full-spectrum hot-water extract. The finished extract provides more than 40% total beta-glucans.
Zhu Ling is traditionally used in Chinese herbal medicine and is cultivated underground in controlled environments. MycoNutri uses a combination of concentrated and full-spectrum extracts to retain both soluble and naturally occurring insoluble mushroom compounds.

Polyporus umbellatus
NEW & IMPROVED FORMULATION
Polyporus umbellatus (Zhu Ling) has been valued in Traditional Chinese Medicine for more than 2,000 years, first recorded in the Shen Nong Ben Cao Jing as a superior herb.
Unlike most medicinal mushrooms that form fruiting bodies above ground, Polyporus forms dense, tuber-like sclerotia beneath the soil surface — the part used for extraction. These sclerotia are hard and rubbery, developing slowly over 8–12 months before reaching maturity.
Historically, Polyporus was harvested from the wild in forested regions of northern China, but MycoNutri™ sources only cultivated material from Anhui Province, where it is grown in controlled, pesticide-free soil environments to ensure purity and sustainability.
Now produced using 50% high-concentration hot water extract (8-10:1) & 50% full-spectrum hot-water extract both from fruiting body providing a naturally higher level of beta-glucans and dietary fibre derived from the mushroom itself.
This updated formula follows a balanced, natural extraction philosophy, respecting the inherent harmony of the mushroom’s active compounds rather than isolating or exaggerating individual ingredients.
It reflects a holistic approach similar to the Traditional TCM principle of “Jun–Chen–Zuo–Shi”, where each component supports and complements the others to achieve overall balance and efficacy.
The result is a formula that delivers broader nutritional activity and enhanced support for overall wellbeing.
MycoNutri™ Zhu Ling is produced from the sclerotium using a dual hot-water extraction process, followed by vacuum concentration, spray-drying, and blending. The final extract contains more than 40% beta-glucans.

Growing Seasons & Information
MycoNutri™’s Polyporus umbellatus (Zhu Ling) is cultivated in Anhui Province, China, using buried hardwood sawdust and soil-based substrate.
The cultivation process mimics the natural environment: hardwood chips are inoculated with Polyporus culture, then buried underground where they remain undisturbed for most of the year.
Over time, the sclerotia gradually form and harden, drawing nutrients from the substrate while developing their unique composition. Harvest occurs once annually, when the sclerotia reach full density and uniform size.
This underground cultivation method mirrors the growth habits of Poria cocos (Fu Ling) but produces smaller, darker, and more resilient sclerotia, rich in functional compounds.
Raw Material manufacturing process
The sclerotia are cleaned, dried and ground before extraction. Due to their tough, rubber-like texture, extraction requires extended hot-water decoction under controlled pressure to release the bioactive polysaccharides and sterols.
High concentration 100% extract
* Hot water extracted twice using controlled-temperature hot water to release polysaccharides and protein-bound fractions.
*Extracts are filtered and vacuum-concentrated to preserve molecular integrity.
*Spray-Drying
*Concentrated extracts are spray-dried without fillers, producing a clean, soluble powder.
No carriers, no starch, no maltodextrin.
Fully soluble.
Full Spectrum Extract
* Hot-water extraction to obtain soluble β-glucans and polysaccharides;
*A proportion of finely milled mushroom fibre is reintroduced to retain insoluble β-glucans and the mushroom’s natural matrix.
The combined extract is spray-dried under controlled conditions, producing a balanced, full-spectrum extract free from excipients or maltodextrin ensuring both potency and authenticity.
