Susun Weed recommends drinking Nettle infusions daily. Mountain Rose sells the best quality (certified organic & kosher!)
From Susun Weed’s website: An infusion is a large amount of herb brewed for a long time. Typically, one ounce by weight (about a cup by volume) of dried herb is placed in a quart jar which is then filled to the top with boiling water, tightly lidded and allowed to steep for 4-10 hours. After straining, a cup or more is consumed, and the remainder chilled to slow spoilage. Drinking 2-4 cups a day is usual. Since the minerals and other phytochemicals in nourishing herbs are made more accessible by drying, dried herbs are considered best for infusions.
