Ugly plants have higher pollen counts!

15/07/2013 //  by Michelle Berridale Johnson//  3 Comments

PlantainThe uglier the plant or flower, the more allergy-inducing its pollens tends to be! What a lovely neat theory being propounded by Dr Robert Valet, assistant professor of Medicine and an allergist at Vanderbilt University – and reported in Science Daily.

Although it seems rather beastly to plants such as this broad-leafed plantain, he has a point. Colourful, highly scented flowers such as those below (how could I resist the opportunity to display a couple of my garden favourites) attract insects who collect the pollen on their bodies and transport it to other flowers where they deposit it. Flowers or plants that cannot attract those insects with their scents or their colours have to use the wind to disperse their pollen.

But for those humans who react to the pollen, this is BAD news as it means that, in season, the air is laden with sneeze-inducing pollens being blown from one plant (or grass or tree) to the next one with which it wishes to mate.

Not that Dr Valet is the only one to make this point. Our own Tom Ogren has made it a number of times in his books and in the gardening section of the FoodsMatter site. If you are interested in how to reduce the pollen producing potential of your own garden (you can do little about public spaces but you can about your own) check out our article about low- allergen gardening or any of Tom’s pieces.

Meanwhile, what insect with eyes in its head could resist some of these…..

    Do you know Michelle I was weeding out those broad leafed plantains and had such a bad allergic reaction, hives, eyes pouring, itching face. Had to wash and lay down in the shade. (It was too hot and also a good excuse to pack in the gardening and enjoy the weather). Never knew they were allergenic…

    And they are such horrid little plants too! I am always digging them out of my lawn. So sorry that you had such a bad reaction, Ruth – but it does make the point. You would not have got that form one of my poppies or delphiniums!!!

FSA – on the allergy case

You might well have thought that COVID concerns had taken over all branches of government activity – but not so. The Foods Standards Agency, while noting the issues, has refused to be distracted from its Food Hypersensitivity work. What is also good to realise – although I suspect that few do – is that all …

Homeopathy – a second string to our vaccination bow?

Cuba has always had a very individualistic– and on the whole very successful – approach to public and population health. The hard line socialist nature of their politics, especially in early days after the revolution, resulted in very high levels of education and medical care – but also in isolation from much of the developed …

Sad, sad news

Yesterday evening, Lisa Acton – co founder, with her husband John Burke, of the Irish FreeFrom Food Awards – finally lost a long and heroic battle with cancer. To my regret I had only met her a few times. A couple of years ago when John brought the whole family to a FreeFrom Food Awards …

Are COVID vaccines safe for those with allergies?

Allergy reactors are, understandably, worried as to whether they should accept a vaccination if and when it is offered. After consultation with the BSACI (British Society for Allergy and Clinical Immunology) the MHRA (Medicines  and Healthcare products Regulatory Agency) have updated their original warning that those with allergies to vaccines, drugs and food should not …

Disastrous Brexit fallout for medical cannabis users

Thanks to the tireless campaigning of a group of  ‘epilepsy mothers’, lead by Hannah Deacon, the mother of Alfie Dingley, and her consultant, neurologist Professor Mike Barnes, a change in the law in 2018 allowed the prescription of medical cannabis for children with certain rare types of epilepsy, those in chronic pain and for those …

The trouble about gluten-free oats

Oats are delicious – oats are nutritious – they contain high levels of vitamins, minerals and antioxidants and are an excellent source of fibre – they do not contain the protein gliadin, the gluten fraction that coeliacs need to avoid – they add texture to gluten free baking and are easy to cook with. Few …
