Beth Mole at ArsTechnica has an article about the levels of belladonna in homeopathic teething products made by Hyland's:
After investigating reports that more than 400 babies were sickened and 10 died in connection with homeopathic teething products, the Food and Drug Administration confirmed Friday that it had indeed found elevated levels of the toxic substance, belladonna, in the products.
Belladonna, also known as deadly nightshade, was the prime suspect of the investigation from the beginning, which Ars reported about last fall. Nevertheless, the products' maker, Hyland's, would not agree to recall the products when it was notified of the FDA's conclusion, the agency reported
In a response to Ars, Hyland's has acknowledged that there are some inconsistencies in the amount of belladonna in its products, but the company said that it has not seen any evidence from the FDA indicating that the elevated levels were toxic or excessive. [...]The FDA said it had found inconsistent amounts of belladonna in Hyland's products. Some of the amounts were "far exceeding" what was intended.
[...] As before, the FDA is urging parents to avoid the homeopathic teething products and toss any already purchased. The FDA does not evaluate or approve the homeopathic products, which have no proven health benefit.

The actual expected concentrations:
Hyland’s Baby Nighttime Teething Tablets -- Belladonna 12X HPUS [hylands.com]
Hyland's Baby Teething Gel -- Belladonna 6X HPUS [hylands.com]
Again from the wiki:
...So it looks like the gel is supposed to have about 1 trillion molecules, while the tablet is supposed to have approximately one.

oops wrong scale. (I used the C not X scale for my conclusion)
From the website:
Belladonna 6X HPUS (0.0000003% Alkaloids, calculated):
-> 1/3x10e-9 -> 1: 333 million
Belladonna 12X HPUS (0.0000000000003% alkaloids, calculated)
-> 1/3x10e-15 -> 1: 333 trillion

I bet the levels weren't so much inconsistent as the were individually adjusted to the levels of latent lycanthropy in the patients under consideration. That's why it had to be put back on the market -- the master lycanthrope is still on the loose.

I'm pretty sure people might think twice about purchasing it if they called Belladonna by its other name, deadly nightshade. From Wikipedia [wikipedia.org]:
And the first sentence under Toxicity:
I'm at a loss for words.

It can't be that bad, otherwise our wonderful governments would have illegalized it as they have other harmful herbs.

The article you linked has seven paragraphs enumerating uses for the plant, or extracts of it, in conventional medicine.
