Which enzyme found in papaya is known to aid in pain treatment?

The enzyme associated with pain treatment found in papaya is papain. This enzyme is a proteolytic enzyme, meaning it helps break down proteins. Due to its anti-inflammatory properties and ability to promote healing, papain is often used in both traditional and alternative medicine settings to alleviate pain. It assists in reducing inflammation associated with various conditions, which can contribute to pain relief, particularly in sports injuries, arthritis, and similar ailments.

Bromelain, another enzyme mentioned, is derived from pineapples and is recognized for its anti-inflammatory effects, but it is not the enzyme found in papaya. Nattokinase is an enzyme derived from fermented soybeans and is primarily known for its effects on circulation and cardiovascular health, while amylase is an enzyme that helps digest carbohydrates. None of these enzymes share the specific pain-relieving attributes that papain is known for, making papain the correct choice in this context.
