Cold sores (fever blisters) are painful, fluid-filled blisters—usually on or around the lips—caused by the herpes simplex virus (HSV). Even though HSV remains in the body long-term, many natural remedies and targeted supplements can reduce pain, shorten healing time, and help prevent frequent outbreaks. This guide covers what to do at each stage of a cold sore, what many people find works quickly, and what Earth Clinic readers commonly report.
Important: Cold sores are contagious, especially from the tingling stage until fully healed. Avoid kissing, oral sex, sharing lip products, towels, cups, or utensils during an outbreak. Wash hands after touching the area.
