Joe-pye-weed

Gravel root is also called queen of the meadow or joe-pye-weed. It exhibits a specific influence on the genitourinary organs. Historically, it was believed to dissolve kidney stones, hence the name gravel root. It is useful for urinary calculi or gravel, but it is not effective for diminishing kidney stones. It is, however, useful for chronic irritation of the bladder, kidney, and prostate, especially if there is pain on urination, a sensation of obstructed urinary flow, and difficult drop-by-drop passage of urine.
