The abundant astringent (substances that contract body tissue) makeup of raw guava and guava leaves helps loosen the bowels and can reduce the symptoms of diarrhea and gastroenteritis. Being highly alkaline, the guavas act as a disinfectant, removing excess mucus from the intestines and inhibiting microbial growth. For these reasons, guavas can also be used to treat dysentery. The guavas’ plentiful supply of vitamin C, carotenoids and potassium can also boost your digestive system.
Thyroid health
A good substance for regulating the thyroid’s metabolism is copper, which guavas have plenty of. The thyroid glands regulate important hormones and organ system functions, which helps maintain a healthy balance in your body.
Healthy brains
Also present in guavas are high amounts of vitamins B3 and B6. These both have benefits for the health of your brain. B3, which is also called niacin, is known to help increase blood flow and stimulate cognitive function, while B6 helps preserve normal nerve function.
Scurvy
Guava is your best source for vitamin C. In fact it has four times the amount of Vitamin C found in oranges, which are regarded as the go-to food for this vitamin. The concentration of vitamin C can prevent scurvy, a disease caused by a deficiency of this vitamin.
Constipation
The seeds of guavas, either ingested whole or chewed, are excellent laxatives. In addition to the fruits' substantial amount of dietary fiber, guavas are advantageous for treating constipation. These two sources cleanse your intestines and excretory system and help your body retain water, helping you achieve healthy bowel movements. Frequently snacking on guavas, then, can be beneficial for proper digestion.
Colds and coughs
Drinking the juice of guavas and fresh guava fruit helps in fighting colds and coughs. The astringent quality can lessen mucus, disinfect the respiratory tract, throat, and lungs and reduce microbial activity. The substantial amounts of iron and vitamin C in guavas also help treat viral infections. It’s advised to avoid eating overly ripe guavas when you have a cold or cough as they can actually aggravate them.
Eyesight
The considerable quantities of vitamin A in guavas are extremely beneficial for the health of your vision. This helps slow down macular degeneration, the growth of cataracts and even improve one’s eyesight degradation once it has begun.
Cancer prevention
Guava is also valuable in your diet as a preventative measure against cancerous growths and metastasis. The high levels of an antioxidant called lycopene has been shown to reduce the risk of prostate cancer and inhibit the growth of breast cancer cells. Guava leaf oil is another anti-proliferative extract from the guava plant that has proven effective in reducing cancer growth.
Skincare
Guavas are also fantastic at improving skin texture and keeping your skin looking fresh. Guavas are full of astringents, particularly in fresh fruit and the leaves of the plant. If you rinse your skin with a guava decoction, the fruit can tone and tighten areas of loose skin. Eating the fruit also provides a rich source of vitamins A, B, C, as well as potassium, which are excellent antioxidants and detoxifiers. They can keep your skin glowing, prevent premature aging and wrinkles, and can speed up the healing process of wounds.
