The Best Eyebright: Our Picks
Buying and evaluation criteria for eyebright products
Depending on what you want to use eyebright for, a different product is recommended. When buying eyebright, you should therefore pay attention to various aspects, which we have listed here.
- Internal versus external use
- Tolerance for adults / children / animals
- Combination with other additives
If you choose the right product for you, you can save money and give your body exactly what it needs. We recommend that you pay particular attention to quality, dosage and ingredients in case you are allergic to any of them.
Internal versus external use
Depending on the application you choose, there are different dosage forms. The best product for your needs depends on what you need the eyebright product for. Eyebright products are therefore divided into products for internal and external use.
For internal use, you can choose between teas, capsules and tablets with eyebright. For colds or allergic reactions, eyebright products for oral use can help.
If you are looking for a product for external use, you can choose between ointments, creams, drops, tinctures and more. These are often a good solution for eye and skin problems, when eyebright should be applied directly to the affected area.
Dosages range from 0.05% eyebright tincture to 5% eyebright tincture content in the product. Some manufacturers dilute the eyebright content from D3 up to D6. In the case of eye drops in particular, water or salt solutions are also added so that the product is better distributed in the eye. Depending on the dosage of eyebright, you may need to use the product more often.
The tolerability of the product can also depend on how high the eyebright content is and which additives the manufacturers have added. The package size also determines how long the product will last. If you only need a small amount of eyebright, a smaller pack size or a product with several small ampoules is recommended. If you are unsure of the correct dosage for your problem, consult a doctor or pharmacist.
Tolerance for adults / children / animals
Eyebright products are often safe for adults in small amounts. However, you should check the package leaflet to see if a product is suitable for you. Some eyebright products are not suitable for contact lens wearers, for example, or should be avoided by pregnant and breastfeeding women. Because it is often well tolerated, there are also some eyebright products for children and animals.
However, before using them on children, make sure that the product is suitable for children and that the child does not develop an allergic reaction to eyebright. Products for dogs, cats and even horses can usually be purchased without a prescription. For animals, there are mainly eyebright eye drops that are supposed to help with dry eyes, glaucoma and more. Although good results have already been achieved with eyebright in veterinary medicine, not every product is also suitable for animals. When buying, therefore, make sure that the product is specifically labelled for use on animals.
Combination with other additives
Some eyebright products are combined by manufacturers with other medicinal herbs or other additives. For example, calendula (marigold) is often combined with eyebright, which is said to be particularly helpful in the treatment of wounds.
Hyaluronic acid is found in the connective tissue of the body and occurs naturally in the vitreous body of the eye. This is supposed to make the product better absorbed by the body and the active ingredient from the eyebright better distributed. Alternatively, manufacturers offer eyebright products with liposomal additives. Liposomes are small vesicles that can transport an active ingredient inside them. The membrane of the liposomes often consists of phospholipids, which are found in the body's own cell membranes. Active substances can thus be absorbed more easily by the body.
Guide: Frequently asked questions about eyebright answered in detail
In order to inform you comprehensively about the effectiveness of eyebright and to give you an understanding of the current state of science, we have summarised all the important information in the following sections.
What is eyebright?
Eyebright has small, white flowers with purple veins and a yellow dot on the lower, spreading petals. It grows 5 to 25 centimetres tall, with ovate, toothed leaves. Depending on when the plant flowers, however, it looks different - for example, summer and autumn plants differ.
How does eyebright work?
- Phenolic carboxylic acids(3)
Which of the active ingredients is responsible for the positive effect of eyebright on eye diseases has not yet been scientifically proven.
Eyebright is also often used in homeopathy and as a food additive. (4) Eyebright is considered to be well tolerated, which is why internal use in the form of tea or capsules is usually safe. Some experts are critical of external use, as hygienic application and correct cleaning of the plant are not always given.(5)
When is the use of eyebright useful?
Eyebright is especially recommended for inflammations in the eye. In a scientific study, it was found that eyebright ethanol and ethyl extracts can help in the treatment of eye diseases.(6) However, as the study was conducted in vitro, i.e. not on patients directly, these results need to be further verified.
One study investigated the effect of eyebright on the protection of eye cells. It was found that the eye drops investigated were able to protect the eyes from cell death caused by UVB radiation and improved wound healing. However, since the eye drops examined contained both chamomile and eyebright extract, it cannot be confirmed beyond doubt that eyebright is responsible for the positive effect.(7)
In another study, eye drops with eyebright were used on newborns who had eye discharge, with partial success. The study concluded that eyebright should not be used alone for treatment, but can alleviate symptoms such as watery or irritated eyes.(8)
Improving the appearance of the skin
Euphrasia officinalis also has a reputation in the medical world for improving the appearance of the skin. For example, eyebright can be used to reduce the skin's exposure to UVB radiation and thus reduce skin ageing.(9) In addition, eyebright can help with pimples and acne due to its anti-inflammatory effect. How high the protective factor of eyebright is, however, still has to be scientifically investigated in more detail.
Colds and allergies
Traditionally, eyebright can also be administered for colds and inflammations of the respiratory tract, as eyebright can have an anti-inflammatory effect.(10) Whether eyebright actually has a soothing effect, however, still needs to be scientifically investigated in more detail and proven in further studies.
What types of eyebright products are there?
Dried plants / tea
You can prepare both a tea and an infusion from the dried herbs. Eyebright tea is intended for internal use, infusions for external use.
You can also make compresses from the tea and hold them over your eyes. You have to be careful not to get the tea in your eye, otherwise it can get infected. Hygiene is very important and should not be neglected.
Eyebright capsules are for internal use.
Capsules are taken with some water or other liquid to help them pass into the digestive tract.
Eye drops / spray
Eye drops and spray with eyebright extract are used for external application for eye problems.
Eyebright sprays are sprayed onto the face with the eyes closed. Eye drops are usually dripped directly into the crease of the eyelid at the lacrimal sac.
Ointment / gel
Ointments and gels are suitable for external use in wound healing and for dry skin.
Since the effect of eyebright has not yet been fully researched, you should make sure that you follow the package instructions and your doctor's recommendations exactly when using eyebright products. Otherwise, unforeseen side effects may occur.
What do I need to be aware of when using eyebright?
If you wear contact lenses, you should remove them before using eye drops. Otherwise, the product will not be able to distribute properly in your eye and irritation may occur. In some cases, contact lenses may also become deformed or discoloured.
When using eyebright products for animals, you should make sure that the product is explicitly labelled for use on animals.
Although the use of eyebright on animals is usually safe (12), some eyebright products for humans may contain additives that can be harmful to animals.
Since eyebright has been little researched as a remedy, you should consult your doctor if you have any known pre-existing conditions or health restrictions. You should also be careful if you are already taking other medications, as eyebright may react to them.
How much do eyebright products cost?
|Eye drops or spray||Approx. 6 to 20 €|
|Tea / Herbs||Circa 4 to 30 €|
|Gel / Ointment / Cream||Circa 7 to 15 €|
|Capsules||Circa 20 to 30 €|
Most eyebright products cost around €50-60 per 100 grams or millilitres. Exceptions are teas and herbal mixtures, which you can buy for a little less, as the eyebright is usually not additionally processed.
What side effects can eyebright cause?
What are the alternatives to eyebright?
|Anti-inflammatory||Foods such as lemons, onions, garlic and products with magnesium can have an anti-inflammatory effect. Other anti-inflammatory foods include grains like amaranth and millet or plants like spinach and broccoli. (13)|
|Wound healing||products with arnica or calendula can support the wound healing process. (14, 15) It is important that arnica and calendula are not rubbed directly into an open wound.|
|Improving the skin's appearance||products with salicylic acid applied directly to the skin for acne dry out pimples (16) Drying out the skin makes it look more even, but excessive use can dry out the skin.|
|cold||Echinacea (17) and Zinc (18) have shown good results in clinical trials in the treatment of colds. Echinacea is therefore used in some cough medications.|
Inform yourself in detail in advance about the properties of a product and which active ingredients are used.
Can I collect / grow and prepare eyebright myself?
If you are looking for eyebright yourself, do not collect plants that grow near fertilised fields or near roads. The plants can accumulate pollutants to which your body can react negatively. Also, be sure to harvest only healthy-looking plants without bugs or leaf rot.
Usually, only the above-ground parts of the plants are processed for their healing properties. Also make sure that you clean the plants thoroughly before preparing them. This is especially important if you use them externally, for example as a compress on the eye. If the plants are not clean enough, you will contaminate your eye and it can become inflamed.
