Help promote normal immune response to herpes simplex outbreaks with Echinacea, Astragalus, and Licorice* Triggers for herpes simplex outbreaks can include sunlight, hormonal changes, a weakened immune system and traumatic events such as injury or surgery, or unusual stress levels. When these cold sores or outbreaks occur, they can be inconvenient, uncomfortable and painful. Herp Defense helps manage the frequency and duration of outbreaks, promoting a normal immune response with 12 immune-supporting whole herbs, including Echinacea Angustifolia, Echinacea Purpurea, and Astragalus.* Licorice and Dulse help promote healing and recovery.* Note: sores may still be contagious up to seven days after they heal, so continue use for 1 week after physical signs disappear.
