Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Protease enzymes have been explored as supportive agents for lymphatic congestion, primarily due to their ability to break down proteins and fibrin, which can accumulate and impair lymphatic flow. Scientific interest in proteolytic enzymes (such as serrapeptase, bromelain, and trypsin) for edema and inflammation dates back several decades. Several small-scale clinical studies and animal models suggest that protease supplementation may reduce post-traumatic and post-surgical edema, which is often associated with impaired lymphatic drainage. The proposed mechanism is that these enzymes help degrade excess protein debris and inflammatory mediators in interstitial tissues, thus facilitating improved lymphatic transport and fluid balance. For example, bromelain has been shown in some studies to decrease swelling and improve healing following surgery or injury.

However, the overall quality of evidence is low to moderate. Most studies are small, not always well-controlled, and focus on acute, localized edema rather than chronic or systemic lymphatic congestion (such as in lymphedema). There is a lack of large, high-quality randomized controlled trials specifically targeting lymphatic congestion as a primary outcome. As such, while the scientific rationale and preliminary evidence are promising, the use of protease enzymes for lymphatic congestion remains an adjunctive option rather than a well-established therapy.

In summary, there is scientific interest and some supporting evidence for the use of protease enzymes in managing aspects of lymphatic congestion, but more robust clinical research is needed to confirm their efficacy and safety for this specific indication.
