Right now, I'm a bit leery of any sort of wood finishing chemicals, as I'm about to head to AZ to live in the van for the next 3 months, and any VOCs would destroy my sinuses. It's hard to find a non-allergenic option.
I can see that you don't yet have any background knowledge of what VOC means and what allergies are.
The definition of an allergy is an over reaction to a harmless substance. There is no way to predict what harmless substance you might react to.
But many times what people experience is not an allergy but instead sensitivity to a chemical. An allergic reaction is not the same thing as having developed a reaction to a particular chemical. Not just chemicals in industry, a person can also develop sensitivity to natural chemicals over time through exposure. For instance the smell of the plant with yellow flower known as "Scotch Broom" that bothers a lot of people is not an allergic reaction, it is a chemical sensitivity. The same thing is true of many of the perfumes that are used in laundry detergents, air fresheners and such.
VOC reaction can be a chemical sensitivity reaction as well but it has other health issues associated with it. VOC stands for volatile organic compound. You can read about what it is here

Avoiding VOCs in a finish is dead simple, just buy water based products that have no VOCs in them. Every paint and hardware store sells water based finishes so you will have no trouble finding a suitable finish be it paint or a water based "varnish".
There is yet another category you can look for that will keep you from having issues, that is a product that not only has no VOCs but is also formulated to be very low odor. So I would recommend that you head to a local paint store or the paint department in a Home Center store and ask for a water based, low odor paint or clear finish, you can also get water based stains if you need that option. It will like say low odor right on the display.
Knowing the "keywords" that describe what you want to find makes shopping much easier. In your case it is "low odor water based"
