"The paradox of Thymus Gland is that it is one of the most important organs for boosting our immune system and yet virtually unknown. If it were known, it would be selling like Vitamin C."
The thymus has been a mysterious gland throughout much of history. It was known to exist as early as the first century A.D., but its role would not begin to be understood until much later. The ancient Greeks thought it was “the seat of courage.” During the Renaissance, they decided it had no function. It was not until the 1970s that its role in the immune system started to unfold.
