I am curious about the cause of sleepwalking in children (or in anyone) and any herbs that are a good starting point for remedying this. I read online that it is caused by liver or heart fire and/or yin deficiency. My daughter, age 7, is sleepwalking and the tip of her tongue is red. However, she does have a lot of stinky/sour smells (I asked about this in one of our classes) coming from head, feet, and armpits, and she gets angry easily, which makes me think of the liver. Thanks!
