When taken by mouth, guava fruit is generally safe to consume as a food. It is a nutritious fruit that is enjoyed by many people without any adverse effects. However, when guava fruit or guava leaf extract is used as a medicinal product, there may be some possible side effects to consider.

1. Nausea and Stomach Pain: Some individuals may experience temporary nausea or stomach pain after consuming guava leaf extract. This can vary from person to person and may be more likely to occur if consumed in large amounts or if the individual has a sensitive stomach.

2. Allergic Reactions: Although rare, allergic reactions to guava fruit or guava leaf extract are possible. Symptoms may include itching, hives, swelling, difficulty breathing, or even anaphylaxis in severe cases. If you have a known allergy to guava or any other related fruits, it is best to avoid consuming guava products.

3. Blood Sugar Effects: Guava fruit is known for its low glycemic index, meaning it does not cause a rapid spike in blood sugar levels. However, if you have diabetes or are on medication to control blood sugar, it is recommended to monitor your blood sugar levels closely when consuming guava or guava products.

4. Drug Interactions: Guava leaf extract may interact with certain medications. It is always important to consult with a healthcare professional before using guava leaf extract if you are taking any medications, especially those that are broken down by the liver.

It is worth noting that these side effects are generally mild and temporary. However, if you experience any concerning symptoms or have any doubts, it is always best to consult a healthcare professional for personalized advice.

Guava fruit is generally safe to consume as a food, while guava leaf extract may cause temporary nausea or stomach pain in some individuals.
