Bromelain is a natural enzyme found in the pineapple plant, particularly in its stem and fruit. It is known for its ability to break down proteins, which can aid in digestion. This enzyme is often used as a dietary supplement and is believed to have anti-inflammatory properties, making it popular among those seeking relief from conditions like arthritis or sinusitis. In addition to its digestive benefits, bromelain is also studied for its potential therapeutic effects. Some research suggests it may help reduce swelling and bruising after surgery or injury. However, more studies are needed to fully understand its effectiveness and safety.
