am not sure of an answer to your question, but my guess is it might
be
that the skin, unlike the stomach, does not utilize hormones,
enzymes, or antibodies. Therefore, boiling does not damage these
elements, as far as the skin is concerned. For topical use, I prefer
synthetic feed grade urea, available at most cattle feed stores for
only twenty cents a pound.

Distillation of urine makes it more concentrated, which naturally
will deliver more nutrition through the skin. This practice of
rubbing urine on the skin, began with the founder of modern Urine
Therapy, John W. Armstrong, who wrote a book called "Urine Therapy".
Armstrong used aged urine, which stinks terribly. The distilling of
urine for topical use is better and less smelly.

Armstrong noted that people on long fasts often suffered from heart
palpitations, and that one can absorb nourishment through the skin,
without breaking the fast, and that the palpitations or Cardicac
Arrhythmia would thereby stop. So now you know how to "cheat" on a
fast.

The skin also absorbs sunlight to make Vitamin D, and even breathes.
If you paint the body in oil paint, thus blocking the pores, it can
soon kill you, since the skin is not only for excretion, but
absorption of air and nourishment. Have you found, in the Pali
Tipitaka, where the Buddha recommends urine therapy? - Dr. Jhani

are somewhat too exaggerating for me. It's very educating nonetheless
on the application of shivambu. One thing I don't quite understand is
why boil shivambu down to a quarter for external application. Care to
explain?
