Nutritional treasures of guava:

1. The Oral hygiene toner: 

Guava extract combats oral plagues without interfering with the oral cavity's natural balance. It prevents germs from sticking to the mouth cavity, limiting the spread of the plague. Gum bleeding is the second most common condition associated with the buccal cavity (scurvy). Guava contains a high content of vitamin C, up to four times that of oranges, making it an effective treatment for scurvy. Its astringent characteristics make it suitable for treating toothaches and ulcers. For rapid relief from toothache, consume the leaves immediately. Guava leaves can also be used to alleviate bad breath due to their high folate content.

• Guava a therapy for cold and cough:

Guava leaves can effectively treat colds and coughs. Guava's high ascorbic acid and iron content reduces lung congestion and mucus production, while also protecting the respiratory system from germs. Guava's components have been shown to treat influenza with remarkable effectiveness. Fruit, particularly raw fruit or a decoction made from young leaves, can alleviate colds and coughs. It acts by dissolving mucus polymers, reducing coughing and mucus production. Its astringent properties help maintain the respiratory system, throat, and lungs germ-free and reduce microbial activity.

• The Blood Pressure regulator;

Guava fruit's high potassium and fibre content can reduce blood pressure and cholesterol levels when consumed regularly. Guava's high pectin content reduces blood lipids by delaying meal absorption, lowering the risk of cardiovascular disease. Guava contains potassium, which improves heart health by managing high blood pressure and lowering cholesterol.

• The cancer protector:

Guava contains high levels of Lycopene, an antioxidant that can help prevent and treat cancer. Breast and prostate cancer are the most responsive. Guavas with red flesh have higher levels of lycopene than other types. Lycopene scavenges free radicals and prevents their further production.

Guava fruit and leaves include flavonoids and saponins that can help reduce stomach acidity and ulcers.

• The wound healer: 

Using a methanolic extract of guava leaves twice daily resulted in faster wound healing due to its tannins and flavonoid content. Research suggests that guava leaf-based ointment can cure wounds faster than commercially available alternatives. The leaves are cleaned, crushed, and extracted using oil. To improve absorption, the extract is frequently combined with a carrier, such as melted candle wax. The final combination is applied twice daily for four days directly to the wound.⁴
