A bowl of berries, a spray of flower essences. They're among the newest products on the market designed to give your immune system a boost -- naturally. Andrea Donsky, co-founder of NaturallySavvy.com, says it boils down to reducing stress.

"Getting nervous about something and creating that fear around and anxiety around it, that in itself has a reaction on our immune system," Donsky said.

That's where rescue remedy comes into play.

"You just put two drops on your tongue and it helps to alleviate the stress, it helps to relax you," said Donsky.

So does oil of oregano.

"You can put a couple of drops under your tongue and wait 10 seconds and then take a glass of water," said Donsky.

Less exotic? Berries loaded with antioxidants and tea made with echinacea.

"I'm a big fan of echinacea," Donsky. "If you take it two weeks on, two weeks off, just so you help give your immune system that boost that it needs during times of stress."

A new line of gummy vitamins can also help. So does fish oil, packed with essential fatty acids.

But remember that staying healthy also means avoiding germs, and there's a new natural product for that too -- called "Clean Well" which uses thymus oil instead of alcohol.

"It's just as effective, it's 99.9% effective and you see the same claim on a conventional product and it doesn't dry out your hands the way alcohol would on the conventional brand," Donsky said.

But is there science to back up claims that these products work?

"There is science behind it and the more that natural organic products become readily available, the more people use it, the more research being done, the more science being done," said Donsky.

Getting Married Risks Obesity
June is a popular wedding month, and while most couples try to get in shape for their big day, a new study finds they don't stay that way for long.

Researchers say married couples are twice as likely to become obese as those who are in romantic relationships but don't live together. In fact the risk rises the longer couples are together since they're more likely to have the same eating and exercise habits which could hinder efforts to lose weight.

Experts say it's important to start healthy eating habits at the start of a marriage.

Child Car-Safety Seats
New research shows the direction a child faces in a car-safety seat could dramatically change the injury risk in a crash.

A study published in the British Medical Journal advises parents to keep a child in a rear-facing position until the child is four-years-old.

Researchers say a child's head, neck and spine are more fully aligned in a rear-facing seat and in the event of a crash, forces are then more evenly distributed.
