It remained a mystery for quite a period of time why farmers from the vine growing regions of France almost never suffered from vein disorders. The long-guarded secret from folk medicine was discovered. It was customary for French farmers to collect the red vine leaves which are found in great abundance at the time of the grape harvest and to make infusions and paste-like poultices from them. The infusions were filled into bottles and regularly ingested in small quantities. The paste from vine leaves was used for the topical treatment of swollen, painful and tired legs – with great accomplishment.
