Alternative medicine

Although study results have been mixed, alternative medicine treatments for cold sores include:

• Lysine. An amino acid, lysine is available as an oral supplement and as a cream.
• Rhubarb and sage. A cream combining rhubarb and sage may be about as effective as acyclovir (Zovirax) cream.
• Stress reduction. If your cold sores are triggered by stress, you might want to try relaxation techniques, such as lemon balm extract, deep-breathing exercises and meditation.
• Propolis. Also known as synthetic beeswax, this is available as a 3% ointment. When applied early and often, it might shorten the duration of the breakout.
