Short answer: Horse Chestnut's active compound escin reduces capillary permeability, helping prevent fluid from leaking into surrounding tissue.
Why naming escin specifically matters
Rather than a vague "Horse Chestnut extract" claim, naming the specific active compound gives you something concrete and checkable to research independently.
Why "capillary permeability" is the specific, named mechanism behind bloating reduction
This describes a genuinely specific physiological process — how much fluid leaks from tiny blood vessels into surrounding tissue — directly connected to the formula's bloating claim.
💡 Worth knowing: less bloating & swelling is listed directly among what MeltDrops is formulated to support, tied specifically to this escin-driven mechanism.
