The immune system is THE key, as nature intended. That is a big why I like supplemental oleander extract for anyone wanting to ramp up their immune system. Now, there is no subsitute for eating and living healthily, but oleander extract may be the most powerful immune stimulator on the planet. In European tests in 1985-86 it had six times the immune stimulating activity as did the two most potent patent medicine immune stimulators.
And CS is like having a super auxilliary immune system when you need it.
