Fig Trees

Has anyone had problems with fig trees or figs?
 
The fig leaves ooze latex.

Hi Nic and welcome to the forum. I've never heard of a problem with figs but, be assured, you will hear if there is one.

We have a small fig tree in the garden, I have not had any problems but then if I see the tree or figs oozing sap, I keep clear of it...

Never heard of this either Nic. Don't have a fig tree in garden but my Mum loves figs.

I found the following article on fig trees:
 
http://www.nzma.org.nz/journal/120-1259/2658/
 
The article states "However, anaphylaxis has been reported after eating figs; in some of these cases, this may represent a cross-reaction with natural rubber latex."
 
The article also refers to the following two articles...
 
Dechamp C, Bessot JC, Pauli G, Deviller P. First report of anaphylactic reaction after fig (Ficus carica) ingestion. Allergy. 1995;50:5146.  
Brehler R, Abrams E, Sedlmayr S. Cross-reactivity between Ficus benjamina (weeping fig) and natural rubber latex. Allergy. 1998;53:4026.

Also just found this....
 
Natural rubber products are made from fig tree (Ficus carica) by homogenizing the plants in an acetone/benzene and separating the rubber-containing phase by centrifugation. F. carica contains about 4% (w/v) natural rubber in latex, and 0.3, 0.1 and 0.1 % in bark, leaf and fruit, respectively. Molecular mass of the natural rubber from F. carica is about 128 kD. The latex serum of F. carica contains only a small numbers of proteins, with a 48 kD and a 25 kD protein as major proteins. Similar to Hevea brasiliensis and Parthenium argentatum Gray, proteins participating in rubber biosynthesis of F. carica are tightly associated with the rubber particles. Natural rubber is made using the latex serum and the proteins in latex, leaf, bark, and fruit of F. carica.

Thanks Liz, I didn't know that figs could be a problem.   Whilst looking into this I found an interesting article:
