Hello I have been taking a supplement called ashwagandha for stress issues ,but after a month or so I stated to get breathless, heart palpitations all so anxiety, I haven't taken the supplement for 5 days now but I still feel the same ,in the list of side effects the supplement can stimulate the the thyroid to produce more thyroxine ,do the symptoms I have described sound like to much thyroxine being released into my body?
