Astragalus
Este suplemento esta muy relacionado, con los telomeros y la telomerasa (Ver Cycloastragenol: www.buscandolalibertad.com/post7779.html#p7779), por lo tanto con el rejuvenecimiento de las celulas mediante el alargamiento de sus telomeros.
Es un suplemento usado en China desde hace miles de anios, en China lo usan junto con miel, y es que el astragaloside IV que es el encargado de su principal efecto es dificil de absorber por las moleculas de azucar que lleva unidas, y se sospecha que las encimas de la miel pueden ayudar en este aspecto, la molecula libre es el Cycloastragenol, se puede comprar como TA-65 pero su precio es bastante elevado.
Astragalus (Astragalus membranaceus) has been used in Traditional Chinese Medicine (TCM) for thousands of years. It was often combined with other herbs to strengthen the body against disease. Astragaus is called an adaptogen, meaning it helps protect the body against various stresses, including physical, mental, or emotional stress.
Astragalus may help protect the body from diseases such as cancer and diabetes. It contains antioxidants, which protect cells against damage. Astragalus is used to protect and support the immune system, preventing colds and upper respiratory infections, lowering blood pressure, treating diabetes, and protecting the liver.
Astragalus has antibacterial and anti-inflammatory properties. People sometimes use it on the skin for wound care. In addition, studies have shown that astragalus has antiviral properties and stimulates the immune system, suggesting that it may help prevent colds.
In the United States, researchers have looked at astragalus as a possible treatment for people whose immune systems have been weakened by chemotherapy or radiation. In these studies, astragalus supplements seem to help people recover faster and live longer. Research on using astragalus for people with AIDS has produced mixed results.
Recent research in China suggests that, because astragalus is an antioxidant, it may help people with severe forms of heart disease, relieving symptoms, lowering cholesterol levels, and improving heart function. At low-to-moderate doses, astragalus has few side effects. However, it does interact with a number of other herbs and prescription medications. Astragalus may also be a mild diuretic, meaning it helps rid the body of excess fluid.
People with autoimmune disease should speak with their doctor first before taking Astagalus because it may stimulate the immune system.
Many practitioners recommend against using any single "adaptogenic" herbs over long periods of time. Instead, they might suggest rotating among several "adaptogens" every couple of months.
Lithium — Astragalus can make it harder for the body to get rid of lithium, so dangerously high levels of the drug could build up.

Un hilo sobre como extraer Astragaloside de la raiz: http://www.longecity.org/forum/topic/69 … alis-root/
Just had a quote for 1kg of 98% pure cycloastragenol for US$51,833 not including shipping from China. On a related note, one kilogram of gold is currently only $41,776.
it seems that Astragalis root is cheap (about $15 per pound) available from Amazon from a variety of vendors. The extraction of astragalosides appears to be relatively straightforward :- something that could be done with a home microwave, some ethanol and some basic chemistry equipment … see the abstract below for the recipe. I was wondering if anyone has tried this? Also, iron salts are sparingly soluble in alcohol, so I imagine minimum iron would be retained in the solute. Also, I have read references that many pounds of raw Astragalis root is required to manufacture just 5mg or so of cycloastregol. I’m skeptical of this claim as a external company provides cycloastregol 5mg for $1.15 per tablet. If one tablet is derived from three pounds of astragalis root it would mean they would need to source their root less than 10 cents a pound to be economically viable. Does anyone know the concentration of cycloastegol in the root?

Optimisation of the microwave-assisted extraction process for four main astragalosides in Radix AstragaliThe MAE procedure was optimised, validated and compared with other conventional extraction techniques. MAE gave the best result due to the highest extraction efficiency within the shortest extraction time. The optimal conditions of MAE were: employing 80% ethanol as solvent, ratio of solid/liquid 1:25 (g/ml), temperature 70 °C, irradiation power 700 W and three extraction cycles, each 5 min. Scanning electron microscopy (SEM) images of Radix Astragali materials after different extractions were obtained to provide visual evidence of the disruption effect. This is the first report on combining MAE with LC-ESI/MS for the extraction and quantification of astragalosides I?IV in Radix Astragali. The developed MAE method provided a good alternative for the extraction of triterpenoid saponins in Radix Astragali as well as other herbs.
