Homeopathic Remedies for people with these specific Flu Symptoms:
Arsenicum album: great prostration with extreme chilliness and a thirst for frequent sips of warm drinks. The eyes and nose stream with watery, acrid discharges. Feels irritable and anxious.
Baptisia: gastric flu with vomiting and diarrhea. Comes on suddenly. Feels sore and bruised all over. Profuse perspiration with a high fever and extreme thirst. Feels (and looks) dazed and sluggish.
Eupatorium perfoliatum: the pains are so severe it feels as if the bones are broken. The muscles ache and feel sore and bruised as well. A bursting headache with sore, aching eyeballs. The nose runs with much sneezing, and the chest feels sore and raw. Thirsty for cold water even though it brings on violent chills in the small of the back.
Gelsemium: flu comes on slowly especially when the weather changes from cold to warm. The muscles feel weak and achy. There’s a great feeling of heaviness everywhere—the head (which aches dully), limbs, eyelids etc. No thirst at all. Fever alternating with chills and shivers that run up and down the spine. Feels (and looks) apathetic, dull and drowsy.
Nux vomica: gastric flu with vomiting and diarrhea. The limbs and back ache a great deal. The nose runs during the day and is stopped up at night. Fever with chills and shivering especially after drinking. Very chilly and sensitive to the slightest draught of air or uncovering. Feels extremely impatient and irritable.
Rhus toxicodendron: flu in cold damp weather. Great restlessness: aching and stiffness in the joints is worse for first motion, it eases with continued motion and then they feel weak and have to rest after which they stiffen and have to move again. Pains are better for warmth. Feels anxious and weepy.
