Ayurveda texts and modern research back the following facts:
Asparagus (Shatavari) has potent antimicrobial properties that combat common pathogens involved in UTIs of varied etiologies. It is also an antioxidant, which protects the genitourinary system from oxidative damage. Asparagus elevates the urinary concentration of magnesium, which inhibits urine crystallization (mineral formation in urine).
Indian Sarsaparilla (Sariva) has a renoprotective effect, which protects against chemically-induced nephrotoxicity.
Nut Grass (Musta) has anti-inflammatory and analgesic properties, which soothe the inflamed mucosa and reduce pain due to dysuria.
Small Caltrops (Gokshura) has potent diuretic properties, which increase blood flow to the kidneys. This process increases the amount of water excreted through urination, which is beneficial in combating cystitis and urethritis (swelling and irritation of the urethra).
Please consult your physician to prescribe the dosage that best suits your condition.
