I took a pau de arco and oil of oregano herbal tincture two days after botox to treat a skin infection naturally, I noticed my botox never took effect and I had lots of facial spasms with six hours of consumption. Is it possible for something taken systemically to interfere with the injection since the formula targets bacteria, viruses and fungus? Or am I resistant to botox's effects. It had already been 48 hours, so I assume it would have attached to nerve site by then?
