If you want to prepare guava-leaf tea as a normal beverage, begin with clean, food-grade leaves. Wash them thoroughly, place a small amount in freshly boiled water, allow the mixture to steep for several minutes, and strain it before drinking. Avoid adding large amounts of sugar if you are trying to maintain healthy blood glucose or cardiovascular health.Do not use homemade guava-leaf water as eye drops, eye washes, or compresses unless specifically instructed by an eye-care professional. Homemade preparations are not sterile and can introduce bacteria or irritating plant material into the eye. This can potentially cause conjunctivitis, corneal irritation, infection, or more serious eye problems.
Bloodshot eyes and blurred vision also have many possible causes. Dry eyes, allergies, irritation, infection, contact-lens problems, eye injuries, changes in blood sugar, medication effects, glaucoma, cataracts, and other conditions can produce similar symptoms. Treating the wrong cause at home can allow a potentially serious problem to worsen.
