Hey Kamreen,
There might be an underlying infectious condition beneath the PV.
PV has been associated with HIV,Herpes or Fungal Infections.
For now you can start using Extra Virgin Coconut Oil for "Oil Pulling"
minimum 15' each morning before eating. Some people use it 2x daily.
There no side effects. Just look it up.
Also 2-3 Tablespoons of EVCO daily by replacing other cooking oils or fats
will be helpful as it is Anti-fungal,Anti-viral, Anti-microbial, Anti-parasitic
and more.
You should visit your doctor for an examination and referral to see a specialist.
Wishing you well.
Niko
