Homeopathic remedies do work in many cases, it’s not placebo, there is no scientific explanation so most doctors daren’t use them. They work by switching the immune system on, so if you have a persistent cough that just won’t go homeopathic may help, conditions like Hay Fever, Excema, Digestive upsets, Aches and Sprains, even Depression or Hyperactivity, all respond well.
For infections antibiotics are the first cure but if they don’t work out you can’t get them homeopathic may work. They are cheap and unlikely to do harm, you need a good guide book that tells you which remedy for which condition.
