@aliali Not knowing how much moringa is in two cups of tea, everything i found says 6mg is probably too much. Have you considered the idea that since you were not feeling like this before taking the moringa, that you can experiment and stop taking the tea, to see what will happen in a week or 10 days? It certainly is worth a try, to see if the symptoms go away. If the only medication you are on is Lexapro, I would check with your doctor.
