Poisonous Plant Azalia
Poisonous Plant: Azalea - Are Azaleas poisonous to humans? Yes they are
Azaleas are a sub species of the Rhododendron family. Azaleas and Rhododendrons are ornamental shrubs, grown for their clusters of spectacularly bright and showy flowers and evergreen foliage.
They have potentially toxic leaves and flowers and even the honey from their flowers can be poisonous.
Flowers and leaves contain glycosides, but particularly andromedotoxin. This is a volatile resin which burns the mouth, and thus usually discourages potential victims from consuming dangerous quantities of the leaves.
The human digestive tract is capable of breaking down small doses of andromedotoxins into harmless compounds, so human fatalities from eating these plants are rare. However, victims who consume a lot suffer from nausea, vomiting, abdominal upset, and low blood pressure.
People who regularly eat affected honey may also suffer similar chronic symptoms .

If you Have Irises, Azaleas or Hydrangeas in Your Garden, Don't Panic
I would just mention that I have all these plants in my garden, and have never experienced any adverse effects, and neither has my cat, or anyone I know.
So what can we conclude from this?
Have I been extra careful?
No - until I started researching, I had no idea that these plants were poisonous. I've been aware since I was a child that plants with white sap, like poinsettias, are poisonous, and I learned the hard way that hellebores are poisonous, but these particular beauties - never!
Have I just been lucky?
I will have to answer yes to that. So what do we put my good fortune down to?
All I can say is that I have planted them, touched them, nurtured them and even pruned them without developing any of the symptoms described above. Maybe some people are just more sensitive to noxious substances than I am.....and, of course, I always wash my hands after gardening, and I'm not inclined to lick my fingers or rub my eyes after touching any plants, whether or not I believe they are poisonous.
Has that saved me from being poisoned? Hard to say. But it does seem to be good advice generally.
