I started some ech tincturing a couple months ago and I want to send some to a couple family members but my sister thinks she is allergic based on the fact that when she has taken anything (cough drops) that are SUPPOSED to have ech in them, her nose gets stuffy.
Anyone have experience with this? She is sensitive. She gets much stronger reactions to any drugs or alcohol than I ever have. If it is a 'real' allergy, could my super duper tincture hurt her?
