Corneal ulcer treatment through natural home remedies

corneal ulcer

corneal ulcer is an epithelial defect with underlying inflammation on the cornea or opens sore. The cornea is the clear structure in the front of your eye.

Iris is the colored part of the eye. The cornea overlies the iris.

The aqueous fluid in the eye’s anterior chamber separates the cornea from the iris. The corneal ulcer will often appear as a gray or white opaque or translucent area on the normally clear and transparent area.

In most cases, corneal ulcers are caused by bacterial infections. They can cause corneal ulcers, which are very common in people who wear lenses [1].

There are some studies in which are shown that the bacteria can directly invade the cornea if the corneal surface has been disrupted. Some bacteria produce toxins that can cause ulceration of the cornea.

Also, fungal infections can cause corneal ulcers, which can happen with improper care of contact lenses or overuse of eye drops with steroids. There are some parasites like Acanthamoeba which could lead to corneal ulcers. Some viruses can cause corneal ulcers, such as the Varicella virus (the virus that causes both shingles and chickenpox) and herpes simplex virus (the virus that causes cold sores).

Also, tiny scratches or cuts in the corneal surface can become infected, leading to corneal ulcers. For example, glass, wood or metal, or almost any type of particle which strikes the cornea can cause minor trauma.

Talk with your doctor if you suffer from corneal ulcers before using some of the below-mentioned home remedies. Your doctor needs to know the cause of your corneal ulcers, and the natural treatment of this condition depends on the cause of it. [2]


10 Corneal ulcer home remedy

Tea tree oil

Tea Tree oil is a powerful essential oil, and when applied to the eyelid and around the eye, it can help fight against parasitic eye infections. You should keep in your mind that this type of home remedy should not be placed in the eye.

Scientists are saying that when tea tree oil is used around the eye, then is can be seen improvement in inflammationvision, and tear production, and they have said that the recurrence of a parasitic infection of the eye is rare. [3]

Eye care

During your healing process of corneal ulcers, you need to wear sunglasses and avoid unnecessary eye strain. Also, you should use a moist warm compress on the eyes because it will give comfort and fight against the infection.

You should mix three cups of warm water with ten drops of oregano oil and soak a clean washcloth. You should ring well and then place the washcloth over the eyes for twenty minutes.

Natural cures for corneal ulcer

Colloidal silver

There are some studies in which it is said that colloidal silver can kill germs by binding and destroying them [4]. When you put a couple of drops in your eyes of colloidal silver, then it can kill some types of infections.

This home remedy is generally considered safe, but it can interact with certain tetracycline antibioticsquinolone antibioticspenicillamine, and the popular hypothyroidism drug levothyroxine should be avoided. Before using colloidal silver as your natural treatment for corneal ulcers, you need to talk with your doctor to see if it is suitable for you and the correct dosage [5].


You should take 1000 mg, 3 times a day, of this home remedy when you are fighting against a viral infection. There are some studies in which are shown that L-Lysine (it is an essential amino acid) can help to fight and prevent recurrent viral infections [6,7].

Also, you should include foods that have L-Lysine, such as eggspumpkin seedswhite beanswild tunalambgrass-fed beef, and parmesan cheese, in your diet.

If you want a healthy and easy lunch or light dinner that can help you fight against corneal ulcers, you should make tuna pasta salad with brown rice pasta and wild-caught tuna.


When you suffer from a corneal ulcer caused by an infection, you should take 500 mg of Echinacea 3 times per day. Some studies are proof that this home remedy can help to fight bacteria and viruses and, at the same time, enhances immune system function [8].

This home remedy is generally considered safe, but if you take immunosuppressants or econazole, a popular antifungal medication, you should avoid taking Echinacea supplements.

Also, this home remedy can increase the amount of time it takes the body to break down caffeine, so this is a reason why you should avoid taking caffeine.


When you are fighting against infection, then you should take 50 mg of zinc every day. It has antioxidant properties, which can lessen inflammation and improve the immune system response. Also, this mineral is recommended for people with a risk of ARED (Age-Related Eye Disease).

You should consume foods rich in zinc, such as cocoa powdergarbanzo beansgrass-fed beefpumpkin seeds, and lamb.

Vitamin C

You should take 1000 mg of Vitamin C 3 times a day while fighting against infection because this can help boost your immune system response. This vitamin can boost immunity and improve vision for people with eye inflammation and protect against macular degeneration [9].

Also, you should include foods rich in Vitamin C in your diet, such as citrus fruitskiwired bell peppersblack currants, and guava.

It would help if you enjoyed eating a strawberry kiwi smoothie in the morning because this will boost protein because of the yogurt, and at the same time, kiwi is a great source of Vitamin C.

Dietary changes

You should change your diet when fighting an infection, particularly a fungal infection, because this is the key to healing. If you are diagnosed with a fungal infection, then it is very important to remove the yeast and other fungi from your diet, and you should follow a candida diet which your doctor will prescribe.

You should focus on eating probiotic-rich foods like sauerkrautkefir, and yogurt, and you should boost your intake of fats, protein, and fiber.

Vitamin D

It is a known fact that when someone is fighting against any type of infection, they need to increase the Vitamin D levels in their body. 

People with a corneal abrasion or eye injury and Vitamin D deficiency can be more prone to developing an infection.

You should take high-quality Vitamin D3 supplements after you have talked with your doctor about the correct dosage.

You should try to get a minimum of ten to fifteen minutes each day of direct sunlight without sunscreen.

You should wear sunglasses to protect your injured eyes and focus on consuming foods rich in Vitamin D, such as salmoneelmackerel, and halibut (wild fishes rich in Vitamin D). Also, many studies show that Vitamin D can improve the immune system response, concentration, and mood [10].

Vitamin A

Many studies say that boosting the intake of Vitamin A while you are fighting an eye problem is very important, and this home remedy is at the top of the list for eye and vision health.

It can reduce inflammation.

Also, it can improve neurological function, and it can fight against the damage that is caused by free radicals.

Also, it can fight against poor eye health, which is linked to Vitamin A deficiency.

You should eat foods rich in Vitamin A because, in this way, you will boost this vitamin in your body. Eating three ounces of beef liver will provide you with 3 times the amount of Vitamin A for the daily recommended value.

If you do not want to eat the beef liver, then you can swap it with bell peppersromaine lettuceraw carrots, and sweet potatoes.

If you have decided to take a Vitamin A supplement, then you should remember that this vitamin is fat-soluble and take it with healthy fat for the best absorption.

If you suffer from chronic dry eyes, you should choose natural eye drops with a combination of Vitamin AVitamin C, and Vitamin E, as well as selenium and zinc. They will give you relief from your condition, but they can also help you in the natural treatment of corneal ulcers.
