Hi John/CCJ and others,
Can't seem to find the time to stay on top of these posts, but they sure are interesting. I have never used the concentrated drops or the capsules (the capsules I have been informed are absolutley useless so don't waste your money,) the concentrate has proved to be somewhat useful but does not have the same degree of response as the herbal tea. I agree it would be far easier to just take the drops but I did a lot of research and asked a lot of different herbalists on line etc what they thought and the general concensus seems to be that like many herbs Pau d'Arco has hundreds of different qualities that interact with one another to make a complete synergistic product, no-one as yet even understands exactly how all the properties interact but when you start isolating just one part (even when that part is supposed to be the most benificial) you start to degrade the wholistic medicinal effect. Most Herbalists will tell you it is better to use the herb or botanical in its closest to natural state to get the most benifit, the more we extract and take away the more we interfere with the medicinal interactions. The tea does taste pretty bad but you do get used to it, you can mix it with fruit juice or dilute it with water or add stevia etc as long as you get at least 4 cups per day if fighting something serious like cancer.
Pau d'arco use has been traced back as far as the ancient Incas and Egyptions even the Vikings used it, and it's traditional form is brewed whole as a tea, in my opinion if something ain't broke, why fix it, and anyway Buckleys Cough syrup tastes way worse !!
