I have been reading a number of web pages about alfalfa. It seems that alfalfa is used extensively in India for weak digestion. It is also used for anemia, although some websites claim that excessive use may cause a breakdown of red blood cells. Other websites are also mentioning some negative things about alfalfa use long term. It is hard to know what to believe, and what is an excessive dosage or considered long term. It seems like many of the most potent and effective herbs also comes with warnings about overuse. It is hard to come to a reasonable conclusion. Also people react differently to things. For example, some get relief from chronic constipation and detoxification from psyllium, while others get dangerously clogged up from it, even if they take it with plenty of water, and drink plenty of water for hours later.
