I have lived in Vegas over 6 years and never suffered from allergies until the past couple years. I’ve been to an allergy Dr and had the blood tests and back prick tests and nothing really came back except I was very reactive to histamine. I tried some nose sprays and medicines but nothing seemed to fully help. I decided to try las vegas allergy mix because I like that it’s homeopathic. Through all the windy days this has been keeping my allergies at bay. I take it in the morning and at night or whenever I feel congestion coming on. I hardly ever sneeze and my sinuses have been clear. I have been telling everyone about this stuff!!! TRY IT!!!!
