Dr. Liu is AWESOME! I suffered for years with chronic sinus infections. After multiple surgeries and months of antibiotics, the infections always came back; with that came nausea and sinus migraines that interfered with work. Within 2 weeks of drinking Dr. Liu's tea and acupuncture, I expelled a green plug from my nose and I've been feeling better ever since. Do yourself a favor, go see Dr. Liu- it is worth it!
