Parepin "bootstraps" the immune system. Why use this word to describe parepin? Maybe [[bootstrap]] is meant to reference something else.
In the english English language, to pull one up by one's bootstraps means to assist onesself by one's own means, without outside help or intervention. Bootstrapping, likewise, means to help oneself without outside intervention; Parepin, then, may be promoted as an item that helps the human immune system to assist itself rather than requiring the intervention or help of modern medicine.
