Researching Irish moss (a.k.a carrageen) as a vegan thickener last night (I want to make my home made ice cream thicker), I discovered that the seaweed has many other interesting properties. As well as being an aphrodisiac drink in the Caribbean, it has many superfood health uses - as a natural treatment for bronchitis, a digestive aid, a blood thinner and as a remedy against cystitis. Most interestingly, it is currently being tested as a natural microbicide (in the form of a vaginal gel) protecting against HIV infection. The Population Council in South Africa is currently conducting trials, with the results due out in the autumn. Click here for more.
