Background of the study

Nowadays people are focusing in herbal plants especially those who are common in the environment. One of the examples is the guava plant (Psidium guajava Linn). Based on research this plant is good for healing and treating wounds and other skin infections. So in my research we want to make a bathing soap out of it, because we know that it is effective. People, researchers, scientists were focusing to medicinal plants. They want to prove that there are plants that are more effective against diseases especially in skin. This study refers to a plant that can be made into a bathing soap and improves its quality while using this plant (guava leaves). We want people to handle easily in treating their skin disorders. Instead of boiling the leaves, now it’s easy to apply. Boiling takes much time.

Clinical research has shown that, Praventin, LinumLife and Zinc help improve the look of skin by helping to balance hormone levels and by reducing redness and inflammation associated with a poor complexion.
