185. Five Research-Backed Reasons Why Spiral Herbal Remedies' Reishi Blends Outperform Other Mushroom Supplements

Wild-harvested Reishi from a Connecticut state forest. Unlike factory-grown mushrooms, these specimens are exposed to the elements, forcing them to produce higher concentrations of protective medicinal compounds to survive and thrive in the wild.

1. Targeted Cognitive & Nerve Support via NGF and BDNF Ingredient Focus: Lion's Mane & Reishi — featured in the Reishi Nerve Blend

The combination of Lion's Mane and the Reishi complex is specifically targeted at supporting the brain’s natural capacity for neurogenesis. While Lion's Mane stimulates the production of Nerve Growth Factor (NGF), the polysaccharides in Reishi help up-regulate the expression of Brain-Derived Neurotrophic Factor (BDNF), creating a "neurotrophic environment" that supports the survival of new neurons. This dual-action approach is particularly effective for those looking to improve memory, focus, and overall mental clarity during times of high stress or as part of a long-term strategy for cognitive health

Unlike many products that offer a multitude of mushroom species in their blend, our Reishi Nerve Blend is a precise 50/50 formulation: half the bottle is Reishi and the other half is Lion's Mane. This intentional ratio ensures you receive a clinically significant dose of each mushroom's bioactive compounds rather than trace amounts found in broader multi-mushroom complexes.

Clinical Insight: A study published in Phytotherapy Research showed that adults who took Lion's Mane exhibited significantly improved cognitive function compared to a placebo group. Furthermore, research on Reishi indicates it can reverse decreasing neurotrophic factors, effectively supporting the brain's natural ability to maintain mental clarity and learning outcomes. 👉 Shop the Reishi Nerve Blend

2. Proven Stress Resilience & Sleep Support via Adaptogenic Action. Ingredient Focus: Reishi (three varieties) — featured in all Spiral Herbal Remedies Reishi blends

Reishi has been used in traditional medicine for thousands of years across Chinese, Eastern European, and Native American healing traditions as the ultimate adaptogen. Studies show Reishi helps modulate the HPA axis — the body's primary stress pathway responsible for cortisol regulation — leading to improved sleep quality and strengthened resilience against fatigue.

Clinical Insight: Research indicates Reishi helps suppress inflammatory compounds and supports the body against the physiological effects of chronic stress, promoting better hormonal balance and restful sleep.

Stress-Related Hair Loss Research: A peer-reviewed study published in iScience (Cell Press, 2024) found that Ganoderma lucidum extract attenuated stress-induced hair follicle senescence by scavenging reactive oxygen species, delaying catagen entry, and restoring the expression of hair growth factors suppressed by corticotropin-releasing hormone — a key mediator in stress-induced hair loss. The researchers concluded that GL extract could be a potential candidate for addressing stress-induced hair loss. Read the research here.

3. Immune Balancing, Anti-Inflammatory & Cellular Defense Ingredient Focus: Turkey Tail (Trametes versicolor) — featured in the Turkey Tail & Reishi Blend

Turkey Tail contains polysaccharopeptides, including PSK and PSP, that have been studied for their immunomodulatory, anti-inflammatory, and cellular-defense properties. These compounds are also being researched for their role in supporting the gut microbiome, which is closely connected to immune function. Reishi, Turkey Tail, Lion’s Mane, and Chaga each contribute distinctive compounds to a broader botanical approach focused on immune balance, the inflammatory response, and cellular protection.

Turkey Tail has a particularly well-established history of clinical research. Memorial Sloan Kettering’s integrative medicine resources discuss Coriolus/Trametes versicolor, while medicinal mushroom extracts have been used as adjuncts to standard cancer treatments in Japan and China for more than 30 years. Research continues to examine Turkey Tail’s polysaccharides and their potential applications in immune support and cancer care.

Clinical Insight: Turkey Tail illustrates how a medicinal mushroom can support several interconnected areas of wellness, including immune regulation, gut health, inflammatory balance, and cellular defense. Its research history also makes it an important example of how traditional botanical knowledge continues to inform modern integrative medicine.

4. Antioxidant Powerhouse, Antiviral & Cellular Protection. Ingredient Focus: Chaga — featured in Reishi Maintain

Chaga has been used in traditional medicine for thousands of years across Chinese, Eastern European, and Native American traditions and is recognized as one of nature's most powerful antioxidants. Its bioactive compounds — including polysaccharides, phenols, and triterpenes — are valued for their anti-inflammatory, antihistamine, antimicrobial, and antioxidant properties, and peer-reviewed research is actively exploring their relationship to carcinogenic cellular activity and immune function. Of note, Reishi, Lion’s Mane, and Turkey Tail also contain antioxidant, anti-inflammatory, antimicrobial, antiviral, and immune-modulating properties.

Clinical Insight: Peer-reviewed research is actively exploring the relationship between Chaga compounds and cellular health, immune modulation, and the body's natural inflammatory response. Read the research here.

5. The Gold Standard for Bioavailability: Wild Harvested & Dual-Extraction. Why every Spiral Herbal Remedies mushroom tincture is dual-extracted

The vast majority of medicinal mushroom compounds — including triterpenes — are not water-soluble and are locked inside rigid cell walls. Standard mushroom powders are often unextracted, meaning the beneficial compounds cannot be absorbed. Dual extraction uses both hot water and alcohol to break down those cell walls and capture the full spectrum of bioactive compounds in a form your body can actually use.

We prioritize wild-harvested specimens, such as the Reishi shown here, which we source from pristine forests. Being exposed to the harsh, unpredictable elements of the wild results in higher concentrations of medicinal properties, as the mushrooms produce these protective compounds to survive. Factory-grown mushrooms do not encounter the same environmental stressors and therefore do not have the same exposure.

Clinical Insight: Full-spectrum dual extraction is necessary to obtain both beta-glucans (water-soluble) and triterpenes (alcohol-soluble), ensuring the complete therapeutic potential of the mushroom is delivered. By prioritizing wild-harvested fruiting bodies, we capture a more robust profile of these compounds; unlike factory-grown alternatives, wild specimens are exposed to natural environmental stressors that trigger the production of higher concentrations of protective, bioactive secondary metabolites.

The Science Is Clear.

Donna Cleary has been formulating medicinal mushroom tinctures since 2017, drawing on 13 years as a Registered Nurse at Harvard's Beth Israel Deaconess Medical Center and a hereditary Irish herbalism tradition documented to 1100 AD. These are not trend products. They are precision-formulated botanical tinctures built on thousands of years of traditional use and a growing body of peer-reviewed research.
