I picked my daughter up from a 2 hour nursery when she was about two years old. Don't know if she contracted it that day or before, but she coughed, then had the most awful sounding long whoop' on the in-breath every time. She's not inoculated, phoned NHS line, waited 15 minutes for no answer, was crying as its an eon when your child's sounding like that.
My other half came in and asked what was wrong, (I was crying by now and panicking). "Well give her the homeopathic remedy for whooping cough then", he advised. I put the phone down, and one drosera 30c pilule actually cured her completely by morning. She didn't have any lasting effects or symptoms. I expected to give more pilules than that!
Am still proud, and amazed to this day, especially how quick it worked, its efficacy, and how a tiny pilule can do all that. So glad I learnt it.
