The term guava appears to have been derived from Arawak guayabo 'guava tree', via the Spanish guayaba. It has been adapted in many European and Asian languages, having a similar form.
Guava tree parts giving more advantages than fruits. Basically, following these parts can displays as it appear.
• Roots
• Trunks
• Bark
• Leaves
• Flowers
• Fruits
• Seeds
Guava Fruits
Normally fruits are can see two colors, green and yellow. Sometimes it will be little bit different by countries/ regions. Green ones are unripe and others are yellow. But most of Asian countries guava are green for both. And also divide the fruit by inside color. These are red[6] and white[7]. The outer skin may be rough, often with a bitter taste, or soft and sweet. Varying between species, the skin can be any thickness, is usually green before maturity, but may be yellow, maroon, or green when ripe. The pulp inside may be sweet or sour and off-white ("white" guavas) to deep pink ("red" guavas). Guava fruits, usually 4 to 12 centimeters (1+1⁄2 to 4+1⁄2 in) long, are round or oval depending on the species they have a pronounced and typical fragrance, similar to lemon rind but less sharp. The seeds in the central pulp vary in number and hardness, depending on species.

Nutrition information :-
• Heart Healthy
Guava fruit helps improve the sodium and potassium balance of the body, thereby regulating blood pressure in patients with hypertension. Guavas also help lower the levels of triglycerides and bad cholesterol (LDL), which contribute to the development of heart disease.
• Immunity Booster
Did you know Guavas are one of the richest sources of vitamin C? It's true. Guava fruit contains 4 times the vitamin C content present in oranges. Vitamin C helps improve immunity and protects you against common infections and pathogens. Moreover, it keeps your eyes healthy.
• Improves Eyesight
Due to the presence of Vitamin A, guava is well known as a booster for vision health. It can not only prevent degradation of eyesight, but even improve eyesight. It can help slow down the appearance of cataracts and macular degeneration. Even though guavas are not as rich in Vitamin A as carrots, they are still a very good source of the nutrient.
• Guava during Pregnancy
Guava's benefits pregnant women too as it contains folic acid, or vitamin B-9, which is recommended for pregnant women since it can help in developing the baby's nervous system and protect the newborn babies.

Guava seed
Fruit seeds use for extract natural oil. Guava seed oil, which may be used for culinary or cosmetics products, is a source of beta carotene, vitamin A, vitamin C, copper, zinc and selenium, and is particularly rich in linoleic acid.
Leaves
Guava leaves are oblong to oval in shape and average 7-15 centimeters long and 3-5 centimeters wide. The leaves grow in an opposite arrangement, which means two leaves grow at the same point on either side of the stem, and have short petioles, or stalks that join the leaf to the stem. The surface of the deep green Guava leaf is wide and leathery with faint white veins and some light brown patches. Guava leaves are aromatic when crushed and have a scent similar to that of the guava fruit. Guava leaves grow on a small tree with wide-spreading branches and copper-colored flaking bark that reveals a green base.
Nutrition information :-
• Type 2 diabetes
Guava leaf tea may help prevent spikes in blood sugar and improve symptoms in people with type 2 diabetes. A 2010 review of evidence from clinical trials and animal studies suggests that guava leaf tea may help improve insulin resistance and lower blood sugar levels. These benefits may result from compounds in guava leaf extract helping to moderate glucose absorption after a person eats a meal.
• Menstrual cramps
Taking supplements containing guava leaf extract may reduce menstrual cramps. The results of a study from 2007 Trusted Source suggest that taking guava leaf extract supplements may relieve menstrual pain in women with primary dysmenorrhea.
Participants who took 6 milligrams (mg) of the extract each day experienced less menstrual pain than those taking ibuprofen or a placebo.
• Diarrhea
Guava leaf tea is a traditional remedy for diarrhea in many parts of the world. Evidence from animal studies suggests that the leaf extract may have the potential to treat infectious diarrhea. A 2015 study Trusted Source investigated the use of this extract in mice with infectious diarrhea. The infection cleared more quickly in the mice who consumed guava leaf extract than in those who did not. The researchers noted that guava leaf extract shows promise as a treatment for this illness. Another study from 2015 Trusted Source found that guava leaf extract helped control diarrhea in chickens with Escherichia coli infections. However, scientists need to carry out more research to confirm these findings in humans.
• Flu
Drinking guava leaf tea may help people fight off the flu. In a 2012 test tube study Trusted Source, guava leaf tea showed promise as an antiviral agent for flu treatment. The researchers found that the tea inhibited the growth of the virus that causes the flu. The antiviral effect of the tea may result from the leaf’s flavones, which are a natural antioxidant. Confirming the effects in humans will require further research.
• Blood pressure
Consuming guava leaf extract may help lower high blood pressure. A 2016 test tube study found that the extract had an antihypertensive effect in rat tissues, which means that it may have the potential to reduce blood pressure. This effect may be due to the leaf extract’s antioxidant properties. Antioxidants may lower blood pressure by helping to expand blood vessels. However, scientists need to carry out more studies to determine whether guava leaf extract can reduce high blood pressure in humans.
• Osteoarthritis
Some research in animals suggests that guava leaf extract may benefit people with osteoarthritis. A 2018 study Trusted Source found that consuming the extract protected against cartilage destruction in rats with induced osteoarthritis. However, researchers have yet to confirm this effect in humans.
• Cancer
Guava leaf extract may eventually play a role in cancer treatment. Results of a 2014 test tube, animal, and computer study Trusted Source suggest that compounds in the extract may inhibit the growth of cancer cells. The researchers believe that the effect may occur because guava leaf compounds act like selective estrogen receptor modulators (SERMs). SERMs are a class of drugs that doctors use to treat cancer. They work by preventing cancer cells from multiplying. However, scientists need to conduct clinical trials in humans to better understand the potential for these compounds to combat cancer.
Clinical Overview
Use :-
Clinical trials are lacking. Very limited evidence exists to support guava's use in treating diarrhea, type 2 diabetes, dysmenorrhea, hyperlipidemia, and hypertension.
Dosing :-
Dysmenorrhea: Daily guava leaf extract standardized to 6 mg flavonoid content/day.
Hyperlipidemia and hypertension: 0.4 to 1 kg/day of guava fruit added to the diet for 4 to 12 weeks.
