Guavasteen, also known as guava stone, is the hard seed found inside the fruit of the guava plant. These seeds are small, typically round, and can vary in color from white to brown. They are often consumed along with the fruit, as they are edible and provide a crunchy texture. Guavasteen is rich in dietary fiber and contains various nutrients. In addition to being a part of the fruit, guavasteen can also be used in traditional remedies. Some cultures believe that the seeds have health benefits, including aiding digestion and promoting overall wellness. However, scientific research on these claims is limited.
