Traditional Chinese Medicine's High Regard and Core Functions of Cordyceps
In Chinese herbology, the status of cordyceps is unquestionable. It is a unique complex, formed from the larvae of Lepidoptera bat moths and fungi of the Clavicipitaceae family (cordyceps fungi).
According to traditional Chinese medicine theory, cordyceps is sweet in taste and warm in nature, and it mainly enters the lung and kidney meridians. Its core effects are:
- Tonify the lungs and kidneys, benefit qi and relieve asthma: Traditionally, it is believed to nourish the lungs and kidneys, help calm asthma and coughing, and is commonly used to treat symptoms such as deficiency of both lung and kidney, chronic cough, and asthma.
- Tonify deficiency and strengthen the root: Cordyceps has effects of replenishing deficiency, tonifying qi, and nourishing yin, which are helpful for physical weakness after illness and enhancing physical strength.
- Stop bleeding and resolve phlegm: The Qing dynasty's "Bencao Congxin" records the uses of cordyceps as "protect the lungs, benefit the kidneys, stop bleeding, and resolve phlegm."
Overall, traditional medicine regards cordyceps as one of the three precious tonic herbs alongside ginseng and deer antler, used to consolidate the foundation, nurture vitality, and promote longevity.
Active ingredients and potential benefits under modern research
Modern research attempts to analyze the tonifying mechanism of cordyceps at the molecular level. Cordyceps is rich in various important nutrients and active ingredients, including:
- Rich nutrients: Contains various amino acids (including eight essential amino acids for humans), polysaccharides (about 30%, such as cordyceps polysaccharides), multiple vitamins (such as vitamins E, K, and B complex), as well as various minerals and trace elements.
- Immune regulation and antioxidant effects: Laboratory and small clinical studies have found that cordyceps may help enhance immune regulation, provide antioxidant effects, and slow the aging process. This makes it a popular choice for people concerned about aging and those with weak constitutions.
- Applications for specific diseases: Cordyceps has been studied for improving respiratory health, enhancing physical strength, and combating fatigue. In terms of cardiovascular health, it may help maintain blood circulation, improve myocardial perfusion, and reduce blood lipids and blood pressure. Additionally, for patients with chronic kidney disease (especially diabetic nephropathy), some studies suggest that cordyceps (mycelium) may help restore kidney function.
- Anti-tumor Potential: Although research is still ongoing, the traditional Chinese medicine claim of "cordyceps anti-cancer" corresponds to modern studies showing that cordyceps may help inhibit tumor cell growth and enhance chemotherapy efficacy.
Challenges of Scientific Evidence, Component Myths, and Safety Concerns
Despite traditional high regard, cordyceps still faces skepticism in the rigorous scientific community regarding its effectiveness.
- Lack of Rigorous Evidence: Many studies on the efficacy of traditional Chinese herbs are considered of poor quality and often biased, lacking sufficient rigorous evidence to prove their therapeutic effects. Even an editorial in Nature magazine described traditional Chinese medicine as "full of pseudoscience."
-
Myths About Core Components:
- Cordycepin: Cordycepin is widely promoted as the active component of cordyceps, but a 2017 study confirmed that the true Chinese cordyceps (O. sinensis) does not synthesize cordycepin; this component mainly exists in cordyceps flowers (Cordyceps militaris) and its close relatives.
- Cordycepic Acid: Once considered a signature component, it is actually just mannitol, a common and inexpensive chemical product.
-
Toxicity and Safety Risks:
- From ancient times to the present, Chinese herbal medicine texts have always described the toxicity of certain medicinal materials. Cordyceps products have been tested for slightly high levels of organic arsenic (4.4–9.9 mg/kg), posing a relatively high risk. Therefore, in 2016, the China National Food and Drug Administration removed cordyceps from the health food category.
- Consuming cordyceps may cause gastrointestinal discomfort, allergic reactions, and affect blood coagulation (having anticoagulant effects). Therefore, pregnant women, children, patients with autoimmune diseases, those prone to bleeding, or individuals taking anticoagulant drugs should avoid using it.
The value code of the premium "Nagqu" and current price reference
The price of cordyceps is comparable to gold not only because of its efficacy but also due to its extreme rarity and the irreplaceability of its production area.
Top lineage of Nagqu: Nagqu, Tibet is recognized as the best production area for cordyceps. Nagqu is located in the heart of the Qinghai-Tibet Plateau, with an altitude reaching 4,000 to 6,000 meters, cold climate, and thin oxygen. This unique environment results in higher active ingredient density in Nagqu cordyceps. Nagqu cordyceps are characterized by golden-colored, plump and evenly sized bodies, broad and long tails, and a rich scent of butter or milk.
Scarcity and price trends: Due to harsh growing conditions, difficulty in harvesting, and limited output (recently further reduced by climate change and overharvesting), the market price of Nagqu cordyceps has continued to soar. According to market data, the price of Nagqu cordyceps has increased by over 300% in the past ten years.
Price reference and Hong Kong Dollar conversion (2025 market conditions):
According to the latest market trends (2025), medium-quality Nagqu cordyceps are priced at about 200–300 RMB per gram; while premium-grade cordyceps with well-filled bodies can even exceed 500 RMB per gram.
Based on the exchange rate on that day (assuming 1 RMB is roughly equivalent to 1.1 HKD; this is an estimated rate, please refer to the real-time rate for actual prices), the price of premium-grade cordyceps per gram could reach about 550 HKD approximately.
