OK two snot nosed small people home from school today. HELP!! What can I give them?? They are always getting colds! I'm over c & zinc- see no difference. Tried some bee propolis syrup with them, tasted nasty, they spat it out and did a combo gagging/acrobatic routine. What is sambucol like? Scared to give OTC syrups or anything like that after recalls! Thanks for advice you health saavy Mums!
