Here is some information on DGL studies from Astrid Pujari, M.D.”In terms of relevant studies, the two that I know of were published in the late 1960s and early 1970s. They were small, and didn’t meet the ideal criteria we now use for research studies. These scientists didn’t study heartburn specifically, but found that DGL helped to accelerate healing in people with ulcers.
While the data on DGL for heartburn is fairly skimpy, licorice has been safely eaten as a food, in reasonable amounts, for hundreds of years. Without the glycyrrhizin, the risk is even lower. Given that, it may be worth a try ”as long as your doctor agrees.”
This is very close to my experience. DGL is claimed to be a proven heartburn remedy by many web sites but there is very little ground for that.

These report will be interesting for those who is interested in herb treatments for heartburn and acid reflux.
This summer I discovered a very tasty tea and also a way to naturally relief heartburn. This tea is brewed from marigold flowers.
I got an advice about this tea from a friend and it really made a difference for me.
There are multiple benefits of it:
1) It has no caffeine
2) It has anti-inflammatory, anti-septic properties
3) It has no known side effects
Before trying it I looked at some sources on the net to see if it is true.
Calendula article in wikipedia confirms that calendula has anti-viral, anti-genotoxic and anti-inflammatory properties.
Also I found following article on google scholar http://www.balestramech.com/usa/pdf/DolceDigestivoTech.pdf. This article describes a herb preparation for GI problems treatment and marigold (calendula) is part of it. This article doesn’t look like marketing material but actually has some scientific background. You will also find lots of other herbs which help in treating heartburn and acid reflux.
Also if you’re really into science use google scholar http://scholar.google.com/scholar?hl=en&as_sdt=2000&q=calendula+stomach+inflammation to get scientific proof on calendula properties.
Make sure that you’re getting tea components from professional. I got calendula (marigold) flowers from my friend who is very good in finding herbs.
