I have used cordyceps with my patients for over 10 years to treat fatigue. It is my favorite herb. I even prefer it to ginseng for many people. There is a big variety of quality on the market. I have tested about 10 brands and done research on how the cordyceps is processed.
Another product this company makes is Cordyceps Power What I like about this formula is that it also has other energy tonic herbs in it that make it very strong to boost energy.
The other herbs in Cordyceps Power are:
Proprietary Blend: Cordyceps Mycelia CS-4 Standardized Extract (0.1% adenosine), Astragalus Root, Codonopsis Root, Adenophora Root, Eucommia Bark, Eleuthero Root, Bai-Zhu Atractylodes Rhizome and Ginger Root.
These are some of the top energy tonic herbs used in Chinese medicine. Cordyceps alone is good for urinary issues, such as incontinence, but this formula is much stronger. It has superior kidney tonics in it like Eucommia bark. Eucommia bark is very expensive, so I was surprised to find it in this formula. It is used in Chinese medicine to strengthen the kidney energy and treat high blood pressure in some herbal formulas.
For most patients, I recommend the regular cordyceps extract product from Planetary herbals. When you open the bottle, you will notice the cordyceps is a dark tan and has a nice nutty smell. If you buy another brand, it might be pale. There are cheap supplements made in China from the dregs of the cordyceps extraction process. If it is pale or cream colored, it is not strong and is not worth the money.
