Conjunctivitis, also known as pink eye, is an acute eye infection involving the covering of the eyes (conjunctiva) which is characterised by redness, itching, gritty sensation, and watering of the eyes.  There may also be a purulent discharge, swelling and sensitivity to light.  Conjunctivitis can also be associated with allergies, including hay fever.  Regular bathing with warm salt water will often be helpful.  Homeopathic remedies will resolve the problem swiftly, and the best homeopathic remedy for you or your child’s eye infection is the one that most closely matches the symptoms you are experiencing.

Here are some of the main remedies which are used in the homeopathic treatment of acute conjunctivitis:


Aconite is a remedy which has a marked affinity for the eyes.  It is indicated in the early stages of infections, especially where the inflammation comes on suddenly and violently.  The eyes feel hot, dry and gritty, and are sensitive to light.

Allium cepa

This remedy is made from red onion, and will help in cases of conjunctivitis where the eyes feel similarly uncomfortable, with smarting, burning and watering. There is an irresistible urge to rub the eyes, and they often appear bloodshot.  The eyes are also typically sensitive to light, and the symptoms feel better in open air.


In cases where Apis will be helpful, there is marked puffy swelling of the eyelids, with burning and stinging pain. The eyes water, and tears feel hot.  The whites of the eyes appear bloodshot and swollen (chemosis), and cold applications ease the symptoms.


Dulcamara is often indicated in head colds that tend to go to the eyes, resulting in acute conjunctivitis.  The eyes become red, and there is a typical thick yellow discharge.  The symptoms often come on in or are aggravated by damp weather.


Euphrasia is a remedy made from the herb Eyebright, which has a long history of herbal use for eye conditions.  It also has a strong affinity for the eyes in homeopathic use, and is often indicated in acute conjunctivitis, especially where there is stinging and burning of the eyes, with a thick discharge. The eyes often water, and there is sensitivity to light and a dry gritty feeling in the eyes.

Merc sol

In cases which respond to Merc sol, the eyelids are red and swollen with a discharge which is acrid and burning, irritating the eyes.  Tears are often profuse, and also burn and irritate.  Symptoms are often worse for both heat and cold, and worse at night.  Merc sol is often needed in head colds that go to the eyes, where the symptom picture matches.

Nux vomica

Nux vomica is often called for in acute conjunctivitis with bloodshot eyes and intense sensitivity to light, especially where symptoms are worse in the early morning. The eyelids itch and burn, and they feel better for rubbing. Symptoms may be accompanied by twitching and blinking of eyes.


Pulsatilla is indicated in acute conjunctivitis where the eyelids are inflamed, and especially where there is thick and profuse yellow discharge. The eyes typically itch and burn, causing rubbing.  Symptoms are typically worse in the evening, and in a warm room. It is one of the main remedies for colds that go to the eyes, especially in children, where the symptoms match.
