Maca
The Maca plant (Lepidium pervianum) comes from the highest parts of the Peruvian Andes; growing at a height of over 4,000 meters in strong sunlight and in freezing cold.  The Incas already grew the Maca plant some 2,000 years ago.  In traditional Peruvian folk medicine the root of the Maca plant is known as a vitaliser that improves fertility and works to enhance potency.

Studies on Maca confirm that it encourages a natural increase in sexual potency in both men and women.  Maca root contains the biologically active isothiocyanates that are thought to be responsible for its aphrodisial properties.  Further research also confirmed that Maca improves female fertility as it increases the production of the luteneinizing hormones that are responsible for cell division, and that it increases sperm count in men.

The effect of Maca starts slowly and reaches its full force after one or two weeks.

Oysters
Oysters contain important amino acids, minerals, trace elements and vitamins.  They enforce our immune system, protect against diseases and at the same time provide us with energy, slow down tiredness symptoms, strengthen the brain and support the functioning of liver, gall and bladder.  The metal zinc in the shell improves the synthesis of protein in the cell and the production of the "happyness hormone" serotonin, which makes for a general feeling of well being.  It also increases the production of certain sexual hormones such as androgene and testosterone.  That is why Casanova (1725-1798) mentioned in many of his letters the aphrodisiacal effect of the molluscs.

To enhance sexual potency, fertility and energy it is recommended that Maca root and oysters are taken on a regular basis, for example during a period of 3 to 4 months, followed by a one month pause.
