Belladonna is traditionally used for the symptomatic relief of earache, colds, flu, fever, sore throat, headache, toothache, mastitis etc which come on suddenly with intense, throbbing pain, cramping congestion, bright redness and heat of the face or affected part. Repeat often.
Compare with Aconite for the first stage of the inflammatory process, particularly in small children.

Always read the label. Homoeopathic principles should be applied when using this remedy. If symptoms persist consult your health care practitioner promptly.
