How Long Does It Take For Ayurvedic Treatments Like Shirodhara And Nasya To Cure Blepharospasm?

Hello, Please advise how much time Blepharospasm takes to cure with Ayurvedic medicines .. Shirodhara , Nasya is ongoing. Botox injections did not help when injected twice. Ayurvedic has provided some relief but not sure if it is because of the injection or Ayurvedic treatment but has surely helped. Shall we take Homeopathy along with Ayurvedic Treatment? Please suggest. Age of patient - 42 years Disease - Generalized Dystonia ( Blepharospasm and Cervical Dystonia)
