Does meat tenderizer or MSG help with stings from jellyfish?

Meat tenderizer contains enzymes that can break down proteins, which may help alleviate pain from jellyfish stings by neutralizing some of the toxins. However, the effectiveness of this remedy is debated, and it's important to note that vinegar or seawater is often recommended to rinse the stung area instead. MSG (monosodium glutamate) is not known to provide any relief for jellyfish stings. For serious stings, seek medical attention.
