HelloPharmacist Scorecard of Cultured Cordyceps by Ron Teeguarden's Dragon Herbs

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: cultured cordyceps, a fungus traditionally used in herbal practice. There are no inactive ingredients listed.

Does it work?

Leans against
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: strengthen respiratory power and athletic performance.
  • We looked for evidence on: Athletic performance, Asthma, Cough, Fatigue, stamina, endurance — and 1 related terms.
  • The closest evidence on file: Cordyceps is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Cordyceps is rated "Insufficient Reliable Evidence To Rate" for Asthma, Cough, Fatigue.

The evidence for cordyceps is mixed and often limited. It's rated possibly ineffective for athletic performance.

For sexual dysfunction, arrhythmia, asthma, lung cancer, and chronic obstructive pulmonary disease (COPD), the evidence isn't established in the data we hold — we'd call that insufficient reliable evidence to rate.

The evidence, ingredient by ingredient Cordyceps

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Cordyceps is generally well tolerated when used short-term, though the overall safety evidence is limited and product quality varies widely. The most common side effects reported in research are abdominal discomfort, constipation, and diarrhea, though these are uncommon and may improve if you take it after eating.

There's one case report of liver inflammation (hepatitis) possibly linked to a cordyceps-containing product, though it's unclear whether cordyceps or a contaminant was responsible. There isn't enough safety data to know whether cordyceps is safe during pregnancy or breastfeeding.

Talk with your doctor or pharmacist before using it if you're pregnant or nursing.

Side effects, ingredient by ingredient Cordyceps

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Cordyceps.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 249 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take this product, double-check with your doctor or pharmacist if you're on blood thinners (anticoagulants or antiplatelet drugs) or immunosuppressants — both carry moderate-severity concerns. If you take testosterone, note that a minor interaction is theoretically possible.

The search tool on this page can help you verify your exact medications.

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Cordyceps may be worth considering if you're interested in traditional herbal support, but the evidence for most uses is weak or absent. If you take blood thinners, immunosuppressants, or testosterone, or if you're pregnant or breastfeeding, talk with your doctor or pharmacist before starting.

Check your specific medications on this page first.

Formula

Cultured Cordyceps Reincarnation of Tibetan Cordyceps

Wild Cordyceps sinensis is one of the most precious and expensive herbs in the entire world. The best Cordyceps grows in the Himalayas at around 15,000 feet elevation, just below the snowline. It has been revered in Tibetan and Chinese herbalism as a life-enhancing superstar for centuries. Rare, potent and balanced, more precious than gold, Wild Cordyceps tonifies both the kidney and the lungs and supports sexual functions, brain power, structural integrity, and immunity. Cordyceps is a major lung tonic.

Formulation

It can be used to strengthen respiratory power. It is a powerful athletes' tonic by improving athletic performance and muscle-building capability.

Fortunately, a recent breakthrough in mycoculture has made it possble to "culture" the mushroom in a wild-simulated environment and make it available to the world at a reasonable everyman's price.

General Statements

Previously, the rare supply and prohibitively elevated price of wild Cordyceps make it difficult for most people to consume.

Suggested/Recommended/Usage/Directions

Directions: Add the amount of botanicals per a recipe, as desired, or as directed by a health practitioner. The proper way of extracting botanicals depends on parts used. Flowers, fruits and leaves can usually be steeped or decocted (boiling over fire) while stems, barks and roots typically require decocting. In a Desktop Botanical Garden Glass Tea & Elixir maker, add 1 part botanical(s) and 5-8 parts water, steep or decoct for 5-20 minutes. You can boil water directly in the elixir maker. Repeat this process for 2nd or 3rd extraction until all active constituents have been extracted.

Precautions

Manufactured in a facility that processes tree nuts.

Cordyceps3 drug types · 249 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro and animal research suggests that cordyceps extract inhibits platelet aggregation and function. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.
Animal and in vitro research suggests that cordyceps stimulates the immune system. However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine, which suggests that cordyceps may have an immunosuppressive effect.

Likelihood Possible Evidence B
Testosterone

Theoretically, concurrent use of cordyceps and testosterone might have additive effects.
Animal research suggests that cordyceps can increase testosterone levels. The clinical significance of this finding is unclear.
