Hi! My name is Elaina Greenberg. I'm a licensed acupuncturist and Chinese herbalist. One of the questions I most frequently get asked as acupuncture safe. And the answer is absolutely. All acupuncture needles are pre-sterilized disposable and used only once. And acupuncturists receive an extensive amount of training on human anatomy as well as clean needles. If you have any other questions please come visit my website at www.elainagreenberg.com.
