I am a 22 year old male having recurrent sinus issues from birth. For the past 3 years I have been experiencing fatigue and brain fog, with unexplained speech difficulty for the past 2 years. Have consulted a numbers of ents and neurologists only to be told I have no medical problems, may be its anxiety. So am thinking of trying ayurveda. From my research, I found ashwagandha, yashtimadhu, shankupushpi, vacha and saraswatirishtam to be useful for these problems. Can I take all of them together? Or what combination do you suggest? Thanking you in advance.
