Dry mouth- caused by Ashwaganda???

about 5 days ago I started taking Blessed Thistle in capsule form twice a day, and brewing ashwaganda tea ( 1 tsp per cup) that I sip 3 times a day. I noticed that my mouth has become uncomfortably dry, no matter how much liquid I consume. I started taking these herbs because of severe stress, anxiety attacks, insomnia.
Has any one of you found similar symptoms? Your input would be highly appreciated.
