This query begins with age 30 & ends with 36....
Pruritus or Itching needs a very detailed history and description and perhaps some blood tests etc before we can give you a meaningful suggestion and prescription.
I'm not a big fan of Ayurvedic medicine for this and since I'm not qualified in that line will not comment on your use of it
Evidently it hasn't helped.
Are there any stressors in your life?
Are family members suffering from the same ailment?
Do you travel a lot and can it be possible that you may have contracted bed bugs or such an infestation from someone or from travel, movie halls etc?
Need to check your mattress and bedding & clothing.
Is the itch more at night?
Next Steps
Online Consultation with me with all the above queries answered would be the next logical line to take.
