I hope you don't mind me posting, but I saw you talking about Pau d'arco.
I found a really good brand for use as a tea. The brand is 'WISDOM' - it tastes really fab! There has been some research that shows that the Paraguayan Pau d’Arco used by the Wisdom brand contains 4 X the amount of medicinal flavonoid compounds and bioactive substances” than the Brazilian Pau d’Arco. Irrelevant of the research, when I've drunk this brand, it has felt very uplifting.
I'm really into herbal stuff, and am enjoying some of your posts. Thank you.
