In the advanced stages of Acute, and in Chronic Inflammation of the Bladder, Pareira Brava proves particularly useful. Sir B. Brodie states that he is satisfied that it exerts a great influence over this disease; very materially lessening the secretion of ropy mucus, and diminishing the inflammation of the bladder. He recommends the following formula: - Take of the root ss., add Water Oiij.; simmer over the fire until reduced to Oj. Of this fviij. - fxij. to be taken daily. From exxx. to lx. of the fluid extract may be substituted, if preferred. To this may be added some Tincture of Hyoscyamus; and where there is a deposit of the phosphates, some Hydrochloric or Nitric Acid.
Prout considers that Pareira is undoubtedly one of the best remedies we possess. In Cystirrha it has been given with unequivocal benefit. The above formulae may be employed.
