And the misconception exists that one must offer a lot. This is ridiculous
and dangerous! Usually, only a drop or 2 is sufficient. If one comes in
contact with a spirit that demands more, this is a red flag indeed! I know
with rune work, a female can use the blood associated with her menses
to annoint her runes, but that is a natural flow. Blood-letting in excessive
amounts is dangerous, as it opens one up to infection, diseases, and even
conditions such as anemia, which can be fatal.
