Information 

Burdock is a traditional medicinal herb used therapeutically in Europe, North America and Asia for hundreds of years. Burdock root is traditionally used in herbal remedies to treat
tonsillitis, throat pain, arthritis, rashes, and various skin problems, and as a diuretic, diaphoretic and blood purifier. Burdock Root is one of the foremost cleansing herbs, providing nourishing support for the blood, the liver, and the natural defense system. It’s rich in Vitamins B-1, B-6, B-12, and E, plus manganese, copper, iron, zinc, sulfur, and more.

In Traditional Chinese Medicine, Arctium lappa L. root is recommended as an aphrodisiac agent, and used for the treatment of impotence and sterility.
Also it significantly increases the frequencies of mount, intromission, and ejaculation frequency. 
The aphrodisiac effects of the plant extract may be related to the presence of flavonoids,
saponins, lignans and alkaloids, acting via a multitude of central and peripheral mechanisms.
