My knowledge:

What do you sweat out? Things that are stored in your fat cells.
What is getting stored in your fat cells? A lot, for instance waste materials which your body wants to sweat out, and oils but not vitamins and proteins I know.(you have to take them everyday to for see your body from proteins and vitamins, everything that is too much will be broken down by your liver. Simple to say there is no stock for vitamins and proteins) I also dont think that herbs are getting stored in your fat cells.
So to say I think I've already tackled your theory... Because It won't be stored in your fat cells so you wont sweat it out. Herbs are just available for a certain amount off time in your blood, then they'll get broken down by your liver so you'll pie it out not sweat it out.
You ofcourse can absorb things through your skin so external usage can be helpfull.
More training will make the herbs in your blood go round faster which can mean two things: quicker absorbation or quicker demolition or both.
These are my thoughts

Hmm very interesting!
Your response motivated me to do a little research on my own, because I remembered a few things on sweat from school, but not enough to back up my hypothesis lol.

Vitamins and herbs are either fat soluble or water soluble, so some vitamins do get stored in your fat cells. This is also why it is important to do cleanses so the fat soluble vitamins are not piling up in your system. Herbs are absorbed into the bloodstream through the small intestine.

You were on the right track about fat cells. The secretory "base" is surrounded by adipose tissue (body fat), which also contains many small blood vessels. In recent studies, adipose tissue has been recognized as a major endocrine organ (hormones) and it is responsible for producing hormones --- Estrogen(!!). I had another theory that people with more body fat reached their nbe goals faster than those with smaller body fat percentages..but that's another story lol.
Anyways, sweat is mostly made of water and actually only contains traces of the body's toxins (less than 1%) -- I did not know this -- so next time anyone goes to the gym to sweat out their toxins, you actually aren't doing much work -- your kidneys and liver do the most detoxing. Sweat is derived from blood plasma and blood plasma contains mostly water, dissolved proteins, hormones, etc. etc.

In another study about the medication I was taking that needed to be sweat out of my body to be absorbed through the skin, the results of the study stated: "We conclude that eccrine sweat rapidly transports ketoconazole across the blood-skin barrier, where it may bind or partition to keratinocytes and surface lipids (hair, nails, and lipid-rich sebum)."

Therefore, herbs that are absorbed into the bloodstream do get released onto the skin through sweat and can be absorbed into the skin. However, I do not know how much/what % of the herbs and vitamins one takes will be secreted and absorbed; however, I believe it does help!

P.S. There are two types of sweat glands; I was talking about the eccrine glands (stimulated with heat, exercise, etc. -- in order to regulate the body's homeostasis temperature).
