You should be able to buy it locally, Kava kava is a fairly well established product. If not, through Amazon. As for ayurvedic, I googled "ayurvedic urination" here are some hits: At the bottom of this page there is a list: http://www.allayurveda.com/ail_urinary.asp Another one: http://www.slideshare.net/drsaurabhjpr/ayurvedic-therapy-for-urinary-system-disorders They both mentions herbs I never heard of before.... (punarnava, shatavari,etc)
