I spoke to someone whom treats illnesses in a natural way to pets, and we spoke about allergies.
The person said that an allergy isn't just caused by what is external. Basicly.. lets say you have a pile of leaves. This pile of leaves is at this moment still small enough to fit in your green bin. But when external additions come to this, you'll have move leaves and the bin overflows.
Now.. usually you may not notice a lot but when there is something else that has a triggering effect, and the bin is already full, this can result in allergic reactions.
This person measured it using a bio-resonance test, of which the indicators were changed and different organs were measured for toxic bioelectric readings. Basicly, anything that is off the chart.
Hormonal imbalances can be read too, and it is said to be used to find the cause of a problem that may otherwise not be so apparent or hard to detect.
Now I tried to look a bit more into this. There seems to be some kind of electromagnetic field involved (I could feel that..) There are (for so far I am aware) 2 different devices that are used in this, Bicam and Mora. Bicam method basicly measured healthy waves from a couple of people and has then a set amount of healthy waves which are then given to the body to trigger a healing response.
Mora is different. Mora registers the own bodies resonance and separates the good waves from the bad ones. Then the good harmonious waves are send back to the person.
I think the second system may be better for us as SS, since with power meditation and such we do amplify our own waves. We shouldn't be put down into waves that are.. maybe on a lower level than ours, if you were to choose to go to these.
Which made me think of this. Squares. Satan's Magical Squares. Words, have power, vibration, and their own resonance. If you were to apply the mantra of one of the squares to the place which is giving problems, it is very likely that the problem will lessen if not completely gone by introducing more healthy resoning things.
Anyway, that were my thoughts on that.
Considering what the person told me about the bin thing, it basicly means, that you should work to lessen the burden on your body by in example, cutting out pesticide sprayed foods from your diet. Avoiding plastics. Etc.
There are some herbal teas if you're interested and more ways of treating allergies. But I think the better place to ask this would be on the SS health forum, not here.
Also, before your first allergy became apparent, what happened in the entire year (or more) before that? It may give you a clue as to where to look first to solve the issue.
I also said to look at your natal saturn and any conjunct planets especially that may be taking a beating..
