Support your immune system with castor oil
Boosting your immune system makes you less likely to suffer a herpes attack and a good method is to use a castor oil pack.
Soak two thicknesses of face cloth or hand towel in 1 cup castor oil, then lie down and relax with the cloth over your abdomen. Secure with cling film (plastic wrap) and cover with a heating pad.
Rest for one hour – this is thought to help boost natural immunity.
