It is managed with medicine and therapy. Some people use natural therapies to ease OCD behaviors. They should not be used in place of standard care.
These therapies are likely to ease symptoms:
N-acetyl cysteine is an antioxidant that may ease OCD symptoms.A2, A4
Inositol is a type of sugar that may not have benefit.A5
