First of all, carefully select your raisins. Avoid those that are overly bright, as their shine is often the result of chemical treatments intended to enhance their appearance. Instead, opt for raisins that are darker in color, neither too hard nor too soft, and ensure they are clean.

Wash the raisins and set them aside. Boil two cups of water, add the raisins, and simmer for 20 minutes. Although this step is straightforward, the process does not end here, since the raisins need to be soaked in the water overnight.

The next morning, drain the raisins and reheat the water. You may drink the water hot or warm, based on your preference, but it is crucial to consume it on an empty stomach. Drink the water 30 to 35 minutes before breakfast.

For optimal results, continue this routine for several consecutive days, preparing it overnight so that the raisin water is ready to drink as soon as you wake up the next morning. Stick to this routine for at least four days.

Always select the darkest colored raisins and those that are untreated to avoid any health risks.
