Re: Anaphylactic shock to Yucca

I also recommend that in the future I would avoid capsules since you could also be allergic to the gelatin or the formaldehyde used to harden them.

 I don't remember where I first heard that. I learned that a very long time ago.

Here is a link about it though:

"Capsules

‘Gelatin’ capsules are made from gelatin and various other ingredients. These are manufactured by a number of different

methods (see various patents, and Jones, 1987). The earliest reference to gelatin capsules makes no specific mention of any

ingredients other than the medicines encapsulated (Cauhaupe, 1874). However, current gelatin capsule formulations

contain a wide variety of other ingredients. Each ingredient needs to be addressed on its own merits. One of the earliest

improvements was the addition of sodium carbonate to correct for stomach acidity (Heineman, 1891). At about the same

time, it was discovered that formaldehyde (formic aldehyde) and other aldehydes can be used to harden gelatin capsules

and enable them to pass from the stomach to the intestine (Weyland, 1899). A number of other ingredients have been introduced to harden both soft- and hard-capsules since that invention, but the most extensively studied has been

formaldehyde (Jones, 1987). Improved methods to detect formaldehyde cross-linking are of interest because trace levels of

formaldehyde may have an adverse effect on the capsule contents (Gold, et al., 2001a, and Gold, et al., 2001b)."
