Which exudate is the clear, oily orange liquid that dries (or possibly coagulates) into crystalline forms similar in texture to coagulated blood?
Judging by the color, it could be fibrinous exudate containing high protein as well as lipids. Drying part may be just dehydration as a result of which, super-saturation is achieved at some point resulting is coagulation and gradual percipitaiton of components.--132.198.74.20521:16, 26 January 2007 (UTC)[reply]
Ah that makes sense. I tend to find it coming out of scratched rashes, as well as chronic wounds.
Im being redirected here from transudate. a transudate is not an exudate how may we sort this out?
I agree. The article is self-contradictory, listing serous transudate as a type of exudate and then saying that the two terms are different from one another. Bobsagat (talk) 23:37, 6 February 2010 (UTC)[reply]
Although the source provided includes 'nectar', I'm not sure about that (secretion vs. excretion). Does "exude" include "secrete" AND "excrete"?
And what about insect exudates: honeydew (from aphids), lac (from lac insect, used to make shellac) and manna (dried excretion from some scaly-bug or something).
An interesting example on the 'honeydew' page, from:
Foelling, M; C Knogge and W Bohme. "Geckos are milking honeydew-producing planthoppers in Madagascar". J. Nat. Hist. 2001: 279–284.
Update: "manna" seems to be "lerp", generated by exudativory nymphs of lerp-insects; e.g.:『[Lerp insect] nymphs are sap-suckers, feeding on the sugar-rich sap of the plants on which they’re found. Any waste from feeding is excreted by nymphs as a sweet fluid, and this is woven into shape to then harden in air, forming the lerp.』~Lerp Insects.

The following is moved from lead section. It doesn't belong in the lead (in my opinion) because: 1) it seems to be promoting Biatain® brand, and is cited to Coloplast™ ; 2) it seems to be a copy/paste since it begins with "It is also important...", but there is nothing previously mentioned that is "important" ; 3) some of it doesn't seem to make sense, or is out of context.
It is also important dealing with the control of exudate, removal of unhealthy tissue is key to improvement of the wound's healing process. A good wound cover keeps the wound moist and absorbs exudate at the same time. Thus, locking it inside the cover to prevent maceration. Again, the absorption and retention of the wound are vital towards the healing process and keeping the wound safe. Exudate depurates the wound but the pus, liquid, ext. is left on the skin so it is important for the exudate to be removed carefully. Biatain foam is a type of cover that is made specifically for cleaning these types of injuries. These may be used for up to seven days, controlling all leakage and absorption of the wound.[1]
