I've always understood that Ascaris don't attach either. What I think may have caused some confusion with the head part of it, was the Vervaine post that abundanthealth was talking to Newport about, with the Vervaine (Verbena) tincture...both for Tapeworms and ascaris. When he's talking about the heads, it's for the tapeworms.
The "real vervaine"..the one he says is "Verbena Officinalis", is for tapeworms. The tincture makes them "drunk", and they start dropping their segments. He's talking about it being used together with the Rife frequencies too.
What is confusing, is there are different types of Verbena (vervaine). What is called "Blue Vervain" is the Verbena Hastata. He also says the "extracts" are not what test the best either- that it's best to get the actual, raw herb.
but..then you'll find ones that are further confusing, because it will be the raw herb, like this one, but it names both types of Verbena as the ingredient...and when I showed this to Newport, he didn't like that it said it was grown in Bulgaria.
Of the 3 tinctures already made up on http://www.iherb.com,
the one he said was made right, is this one..and it is the Verbena Hastata type (for ascaris)..but for abundanthealth, has the alcohol she'd rather not have too:
