I thought he meant a replacement benzo not something to completely replace benzos.
Skullcap and chamomile are herbs you can make tea out of that work in the benzodiazapine region leading to anxiety relief although of course nothing close to an overpowered pharmacicutical benzo..... Plus the act of drinking tea is awesome and the act of brewing, inhaling the aroma, and sipping it down can take your mind of anxious thoughts while you focus in prepping and drinking the tea, which again you can do all day as much as you want. Literally you can make a huge batch in a water bottle for the day or throw in a large amount of the herbs in a sealed coffee filter that you refill throughout the day replacing it at the days end, possibly lunch, and in the morning.
