Combination remedies—a mixture of homeopathic remedies aimed at a specific condition, such as colds or allergies—are gaining popularity because they can eliminate some of the trial and error associated with single formulas. Take the common cold, for example. Researching and buying single remedies for each symptom can add up, both in time and money. Combination formulas made by major homeopathic manufacturers now target a range of symptoms associated with various conditions, including menopause, allergies, and insomnia.

“If you try a combination remedy and it’s not working, stop taking it and do some research into single remedies in order to learn which best fits all the changes that have accompanied your symptoms,” says Jody Shevins, ND, of Boulder, Colorado. Or consult a qualified homeopath.
