Is there a natural herb or medicine instead of taking flomax (tamsulosin) for urinary problems?

Saw Palmetto. Saw palmetto has the ability to modestly improve sx. Scientific studies have validated this and it will not hurt to try!
Maybe. Saw palmetto has been shown in some small studies to help with symptoms of prostatism-urgency, frequency, dribbling, small, sluggish stream, but most recent and larger studies do not confirm or validate this. Can try it-if it works, fine. Decrease caffeine, antihistamines, decongestants, stimulants, irritants, e.g. Spicy foods- may help as well. Don't drink liquids for 3-5 h before bedtime.
