There may be new hope for people prone to allergic reactions of the skin. According to a new study, one serving of black raspberries per day could minimize the effects.

In cases of what's known as "contact hypersensitivity," the body's immune system overreacts when a given substance touches a person's skin. This results in the epidermis (the outer layer of the skin) at the contact site becoming inflamed, and thus red and irritated.

While applying ointments such as steroid-based creams may help the swelling go down, scientists at Ohio State University wanted to see if a more natural approach could be used instead. Based on previous research, they already believed that the consumption of black raspberries could reduce inflammation in general.

For the new study, they put a group of mice on a diet that included one serving of black raspberries every day – each serving was the scaled-down equivalent of what would constitute a single serving for a human. A control group of mice received the same diet, minus the raspberries.

After the mice had been on their respective diets for three weeks, the scientists exposed one ear of each animal to irritants that were known to cause contact hypersensitivity. It was found that for the mice that had been eating the raspberries, there was much less inflammation than in the control group.

This outcome was apparently due to the fact that the berries modulate the activity of the body's dendritic cells, which are responsible for transmitting signals to the immune system, prompting it to produce inflammatory responses.

"The immune system is very complex, with multiple players, and so once you begin to identify the unique cells that are being affected by the berries then it helps us to see how berries are inhibiting inflammation," says Asst. Prof. Steve Oghumu, senior author of a paper on the study. "A lot of the bad effects that we see are not always due to the pathogens or allergens themselves, but are due to the way our body responds to these triggers."

The paper was recently published in the journal Nutrients.

I am going out now to get some.
CAVUMark : I make a simple smoothie consisting of a cup of milk,a couple fistfuls of fresh baby spinach,and a cup of frozen blueberries in that order. The supermarket sells frozen mixed berries which include raspberries,I think. Can't remember if they are black. Whatever,berries of all kinds are loaded with antioxidants.
If one looks at Wikipedia for elderberries they are superior to blackberries in many ways so it may be worth considering them as an alternative. They are not a commercial crop but the small trees can be found in gardens and in the wild in much of Europe.

The berries when black should be cut in bunches and frozen to enable you to strip the berries easily from the stalk. Substitute for blackberries in pies for instance. An alternative is of course using the flower for elderflower wine or cordial though in that case you forego having the berries.
