What is Pineapple Extract for?
Bromelain is an enzyme found in pineapple juice and in the pineapple stem. People use it for medicine.
Bromelain is used for reducing swelling (inflammation), especially of the nose and sinuses, after surgery or injury. It is also used for hay fever, treating a bowel condition that includes swelling and ulcers (ulcerative colitis), removing dead and damaged tissue after a burn (debridement), preventing the collection of water in the lung (pulmonary edema), relaxing muscles, stimulating muscle contractions, slowing clotting, improving the absorption of antibiotics, preventing cancer, shortening labor, and helping the body get rid of fat.
It is also used for preventing muscle soreness after intense exercise. This use has been studied, and the evidence suggests bromelain doesn’t work for this.
Some people use a product (Phlogenzym) for arthritis (osteoarthritis) that combines bromelain with trypsin (a protein) and rutin (a substance found in buckwheat). Bromelain used in this way seems to reduce pain and improve knee function in people with arthritis.
There isn’t enough scientific evidence to determine whether or not bromelain is effective for any of its other uses.
What is Pineapple Extract Possibly Effective for?
Arthritis (osteoarthritis) pain and knee function when used in combination with trypsin and rutin (Phlogenzym). This combination seems to be about as effective as some prescription painkillers.
• Knee pain. There's some evidence that taking bromelain by mouth can reduce mild acute knee pain that’s lasted for less than three months in otherwise healthy people.
• Reducing swelling after surgery or injury. Some research suggests bromelain might reduce swelling and pain after surgery or injury. Interestingly, bromelain doesn’t seem to reduce swelling after mouth surgery.
• Severe burns.
• Improving antibiotic absorption.
• Hay fever.
• Preventing cancer.
• Shortening of labor.
• Ulcerative colitis.
