Cordyceps sinensis (CS), a traditional Chinese Medicine, is a fungus that has been historically used for over 2,000 years throughout China and Asia as part of treatment for a variety of conditions, including many cancers. In modern times, the effects of Cordyceps on immune modulation and its use in concert with modern chemotherapy agents, both to enhance therapeutic benefit and to manage side effects, have been widely studied. Cordycepin, one of the active constituents, has been shown to possess many pharmacological activities including immunological stimulation, and anti-bacterial, anti-viral, anti-oxidant anti-inflammatory and anti-tumor effects. It may be of benefit to support cancer patients and cancer survivors.
Available evidence suggests that the efficacy of CS as a potential anti-neoplastic/anti cancer therapeutic agent is related to a role as an activator of innate immune responses.
Cordyceps, like many other medicinal mushrooms has been traditionally cooked into soups in Asia for its nutritive and tonic properties. Like other medicinal mushrooms CS is rich in polysaccharides, the primary immune modulators as well as being rich in vitamins and minerals. It can be thought of as a medicinal food. Cordyceps is best taken as either a water extract (tea or soup) or a high quality powder can be mixed into juice or water, or even into yoghurt or applesauce.
It is important to get high quality, properly prepared and processed Cordyceps product to ensure that you will get the most benefit from this healing mushroom. As with any other product of this nature, seek the guidance of a health care professional.
The constituents in medicinal mushrooms, such as CS, have few drug interactions and can often be used safely along with conventional therapies. Always discuss the use of herbal medicines with your doctor.

RESULTS: Compared with the cells treated with cisplatin alone, cell viability was significantly decreased and the expression levels of VEGF and bFGF protein were significantly reduced in the cells treated with a combination of CS and cisplatin. CONCLUSION: The current study indicates that the polysaccharide of CS inhibits tumor growth in NSCLC and that CS may be a potential adjuvant chemotherapeutic agent in NSCLC therapy.

In summary, CS enhances recovery of mice from leukopenia caused by Taxol treatment. It appears to do so by protecting both hematopoietic progenitor cells directly and the bone marrow stem cell niche through its effects on osteoblast differentiation.

Yeah, I'll try this miracle cure right after I'm done eating Lychee fruit to lose weight. Is it just me or is HP starting to look like it is hosting surrepticious advertisers and passing them off as bloggers?
Not really....more like "has been for a long time".
One aspect that is also often glossed over when it comes to herbal supplements is pharmacokinetics. Simply because you can achieve a result in a dish at a given concentration doesn't mean that you can achieve that same concentration within the human body, especially given that herbal supplements are not often controlled to give equivalent doses of the active ingredient. Then, when you start putting it into the body you then have to deal with absorption of the active ingredient (aka bioavailability), the clearance of the active ingredient due to metabolic processes, and the interaction of the active ingredient with things like plasma proteins.
Overall, it is bad medicine and even worse science to conclude from in vitro or even in vivo mouse data to conclude that there would be anticipated to have any sort of effect in humans.
I'm in favor of requiring that all treatments require the same levels of scrutiny both for efficacy and safety in order to allow them to be prescribed.
