Gradeshnitsa tablets are like little pills that people can take to help their bodies get rid of worms that might be living inside them.
Worms are tiny creatures that like to live inside people's bellies, and they can make people feel very sick if they don't go away.
Gradeshnitsa tablets have special medicine inside them that helps kill the worms, so that they can't live in the belly anymore.
People take the tablets by swallowing them with a glass of water, and then the medicine travels through their body fighting the worms.
It's very important to take the tablets exactly as a doctor or medical professional tells you to, and to always wash your hands and stay clean so that you don't get more worms in the future.
