What are Reishi Mushrooms?

Seasonal allergies or seasonal allergic rhinitis is characterized by rhinorrhea (runny nose), nasal congestion, nasal and ocular pruritus (itchiness), and paroxysmal sneezing. Often, those affected may attempt to find relief with oral or intranasal second-generation antihistamines or an intranasal corticosteroid. Sometimes, if the condition is severe enough, multiple agents must be combined in order to achieve any level of relief.

According to research findings, the extract from the fruiting body of Reishi mushrooms may play a significant role in preventing or treating cold sores. In a study, individuals experiencing recurrent outbreaks of herpes genitalis or cold sores (herpes labialis) were given a herbal mixture containing Reishi, after having received conventional treatments without improvement [9]. The subjects who received the herbal formulation experienced a nearly 50% reduction in the time taken to eliminate symptoms compared to the control group, which did not receive this treatment [9].

Reishi mushroom (Ganoderma lucidum) possesses several important qualities, one of which is its anti-inflammatory properties that hold significant implications for brain health. Chronic inflammation is thought to contribute to the progression of neurodegenerative diseases like Alzheimer's and dementia [12]. By curbing inflammation, Reishi may help protect brain cells and support overall cognitive function.

Reishi's historical significance lies in its ability to induce a calming effect, aiding individuals in achieving restful sleep [19]. Sleep is a crucial aspect of our well-being, and insufficient sleep has been linked to various health conditions [19]. Chronic sleep issues have been associated with cardiovascular disease, obesity, increased mortality rates, and even diabetes [19].

ADHD's hyperactivity component is characterized by behaviors like fidgeting, restlessness, excessive talking, and impatience [21]. Reishi mushrooms' tranquilizing effect and calming properties could potentially be beneficial for individuals struggling to maintain stillness [22].

Studies have revealed that the primary beneficial compounds found in Reishi mushrooms are polysaccharides and ganoderic acids, known for their potent antioxidant and anti-inflammatory properties [28]. The use of Reishi extracts has demonstrated positive effects on skin wound healing, infection mitigation, and the alleviation of conditions like atopic dermatitis and cutaneous sarcoidosis due to its anti-inflammatory functions [28].

Reishi mushrooms possess potent hormone-balancing properties. Studies have shown that an extract derived from the fruiting body of Reishi exhibits estrogen-like activity [31]. This extract has demonstrated the ability to bind to human estrogen receptor alpha and beta, leading to their activation [31].

Research has indicated that Reishi mushrooms may have a positive impact on both male and female fertility. Oxidative stress, caused by an excess of reactive oxygen species or a lack of antioxidants, has been linked to infertility, including sperm damage and male infertility [34].

Reishi mushroom has been extensively researched for its protective effects on the liver. Its hepatoprotective properties are mainly attributed to two bioactive compounds: polysaccharides and triterpenoids [38]. Research has shown that Reishi exhibits strong antioxidant and radical scavenging activity [38]. Oxidative stress occurs when free radicals overwhelm our systems, leading to cellular damage. This is particularly crucial for the liver, as it metabolizes various compounds that produce free radicals. To maintain a healthy liver, adequate antioxidant support is necessary to counteract these compounds and maintain the balance between oxidative and antioxidative processes. Disruption of this balance can result in oxidative stress and cellular damage.

Research has shown a connection between oxidative stress, high cholesterol levels (hypercholesterolemia), and an increased risk of developing cardiovascular risk factors. In the quest to address these factors, scientists examined the impact of Ganoderma lucidum (Reishi) extracts. The study aimed to understand how Reishi might improve cardiovascular health, particularly by reducing high cholesterol levels [39].
