Coniferyl Alcohol - The Evergreen Allergy

...Well.
I have stumbled across something that really doesn't sit well with me...literally. Many of my symptoms and spells of illness have been attributable to a nearly unheard of allergen (although, I suspect it is far more common than is recognised).

Coniferyl alcohol is a phytochemical-a phenolic monolignan, to be specific-that is present many plants. It is derived from the word "conifer" to describe its highest concentration, found in cone-producing trees and shrubs such as pine, spruce, thuja, juniper ect. However, it is also present throughout the world of evergreen plants, in varying concentrations-and in some (not many) seasonal foods, too.

Contact dermatitis and atopic reactions are one most notable symptom of a coniferyl alcohol allergy-as are strong cravings or even addictions to coniferyl foods.

What causes this allergy?
There are several things I suspect..

"In adults up to 60% of all food allergic reactions are due to cross-reactions between foods and inhalative allergens."http://en.wikipedia.org/wiki/Oral_allergy_syndrome

Lignans are phytoestrogens-in other words, estrogen-mimicking phytochemicals in plants...a dominance or I should say excess of estrogen could cause a potential reaction to lignans, as the body reacts in an immunological defense to the potential perpetrator of estrogen toxicity.
Some causes of excess estrogen would be birth control pills-which I was prescribed at the beginning of menses when I suffered severe hormonal distress, and remained prescribed to arbitrarily for 8 years.
Another frequently reported cause are HPV vaccinations-the worst mistake of my life that I made some 5, 6 years ago now?

Another potential is bee stings-yes-coniferyl alcohol is also found in bee pheremones of all things! Indeed, I've had several bee stings..

It is nearly impossible to find one definitive resource for coniferyl foods, in fact the info that can be found is very little and very vague-but I have done much scouring of the internet, and in thus far the foods & substances I have found:

Cinnamon
Maple, maple syrup, pancake syrups
Coconut
Palm i.e. palm oil, jaggery ect
ALL fermented goods-most notably YEAST (this includes brewers yeast & nutritional yeast)
Birch (incl. xylitol)
Olive
Avocadoes
Smoked foods - i.e. cured meat, bacon, smoked salmon, smoked salts, paprika, chipotle
Carob
Flaxseed
Chia
Sesame
Grasses*
Peppercorns/black pepper
Coriander
Brazil Nuts
Pomegranate
Papaya
Pine nuts
Asparagus
Beet
Pineapple
Guava
Lemon
Juniper Berries
Ginko Biloba

*This includes nearly all grains-the coniferyl alcohol is found primarily in the hulls, so if grains are to be consumed, white rice would be preferable to brown rice, ect.
