I'm hesitant for beekeepers to make broad claims but theoretically local honey from your specific area would contain pollens from that area IF the bees worked that particular pollen source.

So assuming a particular reaction to one of those pollens so consuming local honey could desensitize a person to that particular pollen.

However, most hayfever pollens are grass and wind pollinated tree pollens such as conifers, oaks, hickories which for the most part are not preferred by honey bees.

So IMO it's a crap shoot but it can't hurt and honey has many other beneficial aspects.

Never kept bees, but have been known to find a swarm and extract the honey.

Many honeys will darken over time mostly due to oxidation but UV can have negative effects as well. It's particularly noticeable during the extraction process which introduces a good bit of air as it is spun out of the combs. I've seen pure basswood which is as clear as water in the comb, we call it water white, take on a slight hue from just being extracted and bottled.

Sour would indicate fermentation which as said is due to excessive moisture. The reason honey stores well is the bees dry it down below 18%, on average, water content which is to low for yeasts to function. Though that's not a hard and fast as some nectars are notorious for high moisture and can ferment even when capped by the bees and others are much dryer. Commercial packers maintain hot rooms with fans and dehumidifiers to recieve and store incoming honey supers and drums prior to extraction and/or bottling.

Hobbyists can do so on a smaller scale much like we might dry fur.

Fermented honey can be salvaged if caught early or made into mead.

BTW commercial honey is traditionally shipped in 55 gallon drums. Fermenting honey can pop those drums.

For those of us that do make mead...which of those nectars would be good to look for if you can get it fresh enough? We put enough yeast nutrient and energizer in to get things going but its nice to not to have to fight it.

Before I keep bees I heard this and figured it was bs. Then I had development of allergies and they were really bothering me. My wife suggested honey I blew it off. Well when they got irritating enough I tried the local honey she picked up and in a short time no more allergie issues. My thoughts at the time was well probably just went away on its own.

I had similar thoughts when I heard stings helped with arthritis. I thought those people will believe anything. Well I developed arthritis, and became a bee keeper and naturally get stung some. Well my arthritis doesn't bother me during bee season but during winter or even during bee season when I don't get stung for several weeks it starts bothering me again. Is it the bee venom having anti inflammatory properties or the arthritis is only bothersome when I'm not around bees and it's the winter weather ECT?

Personally I believe God provided us with everything we need to fix ourselves on the planet. And I do believe honey and bee venom helps with both. I have nothing but my personal experience. I'm sure there are studies out there on both. But there are also studies saying covid shots are safe and effective. As well as scientists saying things like the science is settled. The most unscientific statement I have ever heard the exact opposite of science in every regard. So I don't put much stock in studies unless I spend a ton of time looking at the method used to get data, sample size, and who funded the studies

Palmetto is known for high moisture and a high natural yeast content.

Id imagine getting palmetto honey would be hard to get up this way
