Thousand Year Ginseng

[Mysterio]

I'm not too familiar with this spell, so I was hoping others could assist me.

1. It sounds like this spell is only useful for the caster, meaning the caster can't target another commander for the spell. Is this true?

2. If a mage is diseased due to old age, will this spell remove the disease? I ask, because the spell description states, "The Thousand Year Ginseng will give the imbiber longevity and good health..." I'm assuming it doesn't.
