Where did Kruschen salts get their name from?

I had enough trouble first working out what Kruschen Salts are/were - the name appears to have originally been a proprietary pharmaceutical product of the British Griffiths Hughes Company, which claimed to increase vitality and wellbeing. According to this site, which belongs to a new company whose Nourish Salts are intended to replicate the no-longer-available-here product, they were

an alkalising blend of mineral salts that may assist in the following:
Cleansing and detoxifying the body
Digestion and keep regular bowel motions
Muscles aches, pains, and cramping
Increasing your dietary intake of iodine so may assist thyroid function
Increasing the alkalinity in the body

So far, so good. However, this medical advice site describes them as just sodium chloride (table salt, listed as one of the range of compounds in the previous listing).

Nobody connected with them seems to care about the origin of the name. The best guess I have been able to make is the German word kruschen, which translates as crumble, or crumbling. Maybe this relates to the fact that the components are crystalline substances that are dissolved into water to make the final product.

It seems to be a bavarian word, meaning to search for something like rummage.

But I guess it is simply the name of one of the producers/sellers of this stuff, as it is a name, too.

It might even been named after Paul Krusch, a geologist, who lived from 1869-1939, At least I see a possible link, working in this field.

To add to the mystery, I Found this entry in "Grace's Guide to British Industrial History"

c.1911 Kruschen Salts were introduced by E. Griffiths Hughes (Kruschen) Ltd to the British market, and to the American market by E. Griffiths Hughes, Inc.
