Alvein

The name of this substance comes from the Latin alveus, which means “lung” or “alveus”. Also the Latin name "Alvein" sounds like "Aleven". Due to the fact that by origin alvein has a natural biological composition, it is externally and chemically very similar to human blood, therefore in ancient times alchemy was used to identify the substitution and establish the fact of the use of poisonous alvein to poison opponents in duels (for example, the Egyptian pharaoh).

Modern science can claim that the biocomposition of alvein looks like this: hemoglobin, proteins, enzymes, lymphocytes, antibodies, erythrocytes (red blood cells), glucose, fats, vitamins. It must contain a sufficient amount of salts and trace elements
