Be careful of these 6 Chinese medicines that may hurt your eyes

Looking at the computer or TV for a long time will not only make your eyes tired, but also cause symptoms such as dizziness and brain swelling. At this time, many people will drink a cup of chrysanthemum tea to protect their eyes, but did you know that the well-known eye-protecting Chinese medicines such as chrysanthemum, licorice, carrots, etc. will hurt your eyes more if used improperly.

chrysanthemum

Chrysanthemum is often consumed as tea, but it can cause severe allergic conjunctivitis. People with a history of allergic conjunctivitis due to hay fever need to be especially careful, as such people are also prone to reactions when taking chrysanthemum. It can be seen that although chrysanthemum tea can nourish the liver and improve eyesight, you must consider whether your physical condition is suitable for drinking it when drinking it.

ginkgo

Ginkgo is one of the most commonly used Chinese herbal medicines. Long-term combined use of ginkgo extract and aspirin may cause spontaneous intraocular hyphema. This is because both ginkgo and aspirin can reduce platelet activity, and their combined effect increases the risk of bleeding.

Licorice

If you take more than 50 grams of licorice per day, toxic side effects may occur. This is by no means a fabrication. A study found that five patients who took 186 to 746 grams of licorice per day developed unilateral or bilateral flash blindness and vision loss, accompanied by headaches and increased blood pressure.

Carrot Herbs

There is no specific research on the relationship between excessive intake of carrots and cataracts, but some scholars believe that excessive intake of carrots may lead to cataracts. Because carrots contain coumarin, psoralen, etc., these substances can become toxic substances under the action of ultraviolet rays. Ultraviolet rays themselves can cause cataracts, and these toxic substances increase the risk of cataract development.

chili

Chili peppers are rich in vitamin A and vitamin C. Some of their extracts can be made into eye drops to treat blepharitis and conjunctivitis. Because it is an irritant, it can worsen the irritation symptoms of conjunctivitis. There have been reports of corneal ulcers in some patients who used eye drops made from high concentrations of chili extract.

Citral

Citral is the main component of lemon balm. Studies have shown that taking small doses of 2-5 mg of citral in monkeys can increase intraocular pressure, and in severe cases, secondary glaucoma may occur. The same toxic side effects may also occur in humans, so caution is required when using it.

In addition to the citral introduced above which can cause high intraocular pressure and glaucoma, other Chinese herbal medicines that can cause increased intraocular pressure and secondary angle-closure glaucoma include henbane plants. Because they can dilate the pupil and cause obstruction to the outflow of aqueous humor. In addition, the commonly used Chinese medicine ephedra can also cause increased intraocular pressure.
