If your sweating is severe, natural treatments may not give you the answer you are looking for…but there is no harm in trying. Firstly, cut out your caffeine intake. Dr Davin Lim says, drink less coffee, and definitely no Red Bull. Go decaf if you can. There are some natural treatments that can reduce sweating by 10-20%, including St John’s Wort, Sage Tablets, and Chamomile tea. Biofeedback using CBT by a psychologist is a excellent method of reducing excessive sweating brought on by stress, anxiety and depression.
