I dunno! They only list the active ingredients: Aconitum nap. 30C, Actaea spicata 6C, Belladonna 30C, Chamomilla 30C, Colocynthis 6C, Kreosotum 6C, Merc. sol. 6C, Nux vomica 6C, Silicea 6C.

Probably some chemical preservative I wonder what preservative the Rescue Remedy for kids uses if it's alcohol free?
