Eyebright tea has a long history in traditional herbal medicine, particularly for supporting eye health. Like many herbal teas, it has attracted scientific interest because of its potentially beneficial properties. People traditionally prepare the tea from the leaves and flowers of the eyebright plant and use it to soothe various eye-related complaints.
Eyebright—More Than an Elegant Wild Herb
Eyebright belongs to the Orobanchaceae family of flowering plants. These small herbaceous plants originate from Europe and western Asia, where they commonly grow in meadows, pastures, and heathlands.
The plant takes its name from its traditional association with eye care. Eyebright usually remains small and produces delicate flowers with distinctive bilateral symmetry. Depending on the species, the flowers may appear white, pink, or violet, often with yellow or purple markings.
The upper edges of the leaves feature multicellular glandular hairs, another characteristic that helps distinguish the plant. Eyebright species can grow as annuals or biennials.
The Euphrasia genus includes numerous species and subspecies that differ in size, flower color, and preferred habitat. Several species grow in Lithuania and other parts of Europe. If you want to use eyebright as an herbal tea, look for Euphrasia officinalis, commonly known as eyebright. Traditional herbal medicine has used this species extensively, and it has received considerable attention as a medicinal herb.
How to Harvest and Dry Eyebright
Proper harvesting, drying, and storage help preserve the quality of eyebright herb and protect its naturally occurring compounds.
- Harvest eyebright during flowering. Pick the herb when the plant reaches full bloom. Choose a dry morning after the dew has evaporated. Use clean, sharp scissors or pruning shears to cut the stems, leaving enough of the plant intact for regrowth.
- Remove damaged plant material. Discard any leaves or flowers that look damaged, discolored, or diseased. Gently shake the freshly harvested herb to remove insects, dirt, and other debris.
- Hang small bunches to dry. Tie small, loose bundles with string or twine. Hang the flowers down in a cool, dark, and well-ventilated place. Keep the herb away from direct sunlight, which can affect its quality. Choose a dry location to reduce the risk of mold.
- Use drying racks when necessary. If you cannot hang the herb, spread it in a single layer on drying racks or mesh trays. Leave enough space between the plant material to promote good airflow. You can also use an electric food dehydrator and select a low-temperature setting.
- Check the herb for dryness. Properly dried eyebright should crumble easily when you handle it. Air-drying may take anywhere from several days to a few weeks, depending on humidity, ventilation, and the thickness of the plant material. A food dehydrator can significantly shorten the drying time.
- Store the dried herb correctly. Separate leaves and flowers from the stems, and transfer them to airtight containers. Label each container with the herb name and harvest date. Store the containers in a cool, dark, and dry place.
Careful drying and storage can help prevent mold growth and slow the degradation of the plant’s naturally occurring compounds. These steps also help maintain the overall quality.
Eyebright Tea and Eye Health
Traditional herbal medicine has long associated eyebright with eye-related complaints such as conjunctivitis and eye strain. The herb contains compounds with anti-inflammatory and astringent properties, which may help soothe irritated tissues.
Historically, people have used ointment to address eye discomfort, including irritation and inflammation. Some people therefore turn to eyebright tea as a traditional herbal option for mild eye discomfort.
However, traditional use does not establish that eyebright tea can treat or cure an eye disease. Anyone experiencing persistent eye pain, significant redness, discharge, vision changes, or other concerning symptoms should seek medical advice rather than rely on herbal remedies.
What Else May Eyebright Tea Offer?
Traditional herbal medicine has used eyebright for various complaints beyond eye discomfort, including digestive problems, headaches, and allergies.
Some cosmetic products also contain eyebright extracts, particularly creams and lotions, which are designed to provide a soothing effect. Research has also explored the plant’s potential antimicrobial activity, which may help explain some of its traditional applications in managing infections.
Traditional herbal practices have also used eyebright for respiratory complaints, including colds and sinus congestion. The herb may have expectorant properties that could support mucus clearance. Certain compounds found in eyebright also show anti-inflammatory activity, which may contribute to the plant’s traditional use for inflammatory complaints.
Eyebright also contains antioxidant compounds that can help neutralize free radicals in laboratory settings. For people interested in plant-based sources of antioxidants, eyebright tea may fit into a varied and balanced diet.
People who prefer traditional herbal preparations may choose eyebright tea for supporting general well-being. However, traditional use and preliminary research do not automatically demonstrate clinical effectiveness, so it makes sense to view eyebright as a complementary herbal beverage rather than a substitute for established medical treatment.
How to Prepare Eyebright Tea and Use It for the Eyes
If you enjoy exploring different herbal teas, eyebright tea may be worth adding to your list. As we mentioned above, traditional herbal medicine has long valued eyebright for its range of potential benefits. You can prepare the tea easily at home using dried eyebright leaves.
Ingredients
- 1–2 teaspoons of dried eyebright leaves
- 250 ml (1 cup) of boiling water
Preparation
- Place the dried eyebright leaves in a teapot, tea strainer, or infuser. Pour the boiling water over the leaves and let them steep for 5–10 minutes. Adjust the steeping time to suit your taste—the longer you steep the herb, the stronger the tea will become.
- Strain the tea before drinking to remove the plant material.
- If you prefer a sweeter drink, you can add a little honey. Lemon can also add a refreshing flavor, and combining eyebright with other herbs lets you create different herbal tea blends. Enjoy the tea while it remains warm.
Can You Use Eyebright Tea Directly on the Eyes?
Traditional herbal practices sometimes recommend using cooled eyebright infusions as an external eye compress. If you choose to follow this traditional practice, allow the freshly prepared infusion to cool completely. Soak a clean, soft cloth, a piece of gauze, or a sterile cotton pad in the cooled liquid. Close your eyes and gently place the compress over the eyelids.
However, homemade herbal infusions do not meet the sterility standards required for products intended for direct application to the eyes. Introducing a non-sterile liquid into or around the eye can increase the risk of irritation or infection. For this reason, avoid using homemade eyebright tea as an eye wash or eye drops. If you have an eye condition, consult an eye-care professional and use products specifically formulated and tested for ophthalmic use.
Possible Side Effects of Eyebright Tea
Although traditional medicine has used eyebright for many years, herbal remedies still require responsible use. Reported adverse effects appear uncommon, but you should still understand the potential risks before adding eyebright to your routine. Talk to a healthcare professional before using eye drops, particularly if you have an existing health condition, take medication, or are pregnant or breastfeeding.
Possible reactions may include:
- Allergic reactions. Some people may be allergic to eyebright or other plants in the Orobanchaceae family. Symptoms can include itching, swelling, skin rashes, or difficulty breathing.
- Eye irritation. Applying eyebright preparations around the eyes or using them as an eye wash may irritate. Homemade preparations may not remain sterile.
- Digestive discomfort. Some individuals may experience mild gastrointestinal symptoms, such as nausea or stomach discomfort.
- Skin sensitivity. Eyebright extracts may appear in cosmetic products, including eye creams and lotions. These products may cause skin sensitivity or irritation in susceptible individuals.
- Pregnancy and breastfeeding. Pregnant and breastfeeding women should avoid using eye drops medicinally unless a healthcare professional recommends it.
- Drug interactions. Herbal products can interact with medicines. If you take prescription or over-the-counter medication, ask a healthcare professional or pharmacist whether eye drops are appropriate for you.
Most importantly, do not use eyebright tea as a substitute for professional treatment of an eye infection or other eye disease. Seek medical attention if you experience persistent redness, pain, swelling, discharge, sensitivity to light, or vision changes.
