Strauss Naturals Prostate Drops contain high quantities of Saw Palmetto Fruit, which provides effective relief of symptoms of Benign Prostatic Hyperplasia. Saw Palmetto Fruit contains high levels of beneficial fatty acids, which over time can solidify in the bottom of the bottle. Normally, shaking before use will effectively mix the Prostate DropsTM; however, if the solids will not mix with shaking, we recommend immersing the bottom of the bottle in hot tap water for approximately 10 minutes and then shake to help remix the fatty acids.
