I found this information.

Although I prefer to eat the fruits, I would like to share the following information, becuase I recommend to eat papaya and pineapple :

Clear·Ease Sinus Enzyme Relief.

A formula of natural enzymes, in precisely measured dose, gives effective relief for sufferers of sinus problems, of problems clearing the ears in flight and in SCUBA diving, inflammation from injury, and in many other problems relating to swelling and inflammation.

What's In It?

Clear·Ease is made of natural fruit enzymes, Papain and Bromelain. Papain comes from the latex of green papaya fruit. Bromelain comes from pineapple stems and fruits. They are called proteolytic enzymes because they break up biological products like thick mucus.

What Does It Do?

Proteolytic enzymes are involved with repair and healing in the body. They have anti-inflammatory action. In the 50's, dozens of clinical trials that showed that these enzymes yielded clear positive results, when they were administered via buccal route, i.e. dissolved slowly between the cheek and gums. Later, however, it was often administered orally, because this was thought to be more convenient. In fact, digestion in the stomach reduced the effectiveness of these enzymes, and they failed to become a popular treatment - until recently.

Papain and Bromelain are used for:

aiding digestion.
(topically) debridement.
mucus liquification for bronchial asthma, chronic bronchitis, otitis media, sinusitis, and infected areas.
vitreous hemorrhages in the eye.
fibrinolysis - dissolving clots including pulmonary embolism.
potentiation of drugs - helps the effectiveness of Antibiotics .
anti-inflammatory effects after injury or infection.
anti-arthritic effects - joint and muscle pain.
There have been hundreds of articles on such enzymatic treatments. Enzymes were found to be especially valuable for the anti-inflammatory effects after injury. There are several modes of action of proteases as an anti-inflammatory agent. There is a reduction in the viscosity of extracellular fluid. There is prevention of excess clot formation. There is an aid to phagocytic function. There is a decrease in anti-inflammatory products.
