Throughout his career, Dr. Weil has recommended herbal remedies far more often than he has prescribed prescription drugs and has said that he hasn’t seen a serious adverse reaction to any of the herbal remedies he has recommended. However, because of the many unsubstantiated claims made for herbal remedies, and because the market is not well regulated, he recommends that consumers follow these guidelines:
Use peppermint essential oil as a cold rub on your chest or inhale it through a vaporizer to help clear nasal congestion and relieve cough and cold symptoms. Peppermint oil may also help relieve tension headache pain. For headache pain, try dabbing a few drops on your wrist or sprinkling a few drops on a cloth, then inhaling the aroma. You can also massage the oil directly onto your temples and forehead. Peppermint essential oil is ideal for muscle and chest rubs, headache pain, dental care, and aromatherapy. You can even add it to your homemade cleaning supplies for extra antimicrobial power and natural fragrance.
Teas are a great way to get the benefits of sage all you need to do is steep one teaspoon of sage in a cup of water for about 10 minutes. You can also make a pretty awesome sore throat reliever by combining sage and thyme. Take an ounce of both grind them, and cover them with 16 ounces of apple cider vinegar. Be sure to shake it periodically and let it sit for ten days before using.
