[Note Guidelines] Photographer's Note
Blessed milk thistle (Silybum marianum) is a milk thistle, a plant of the Asteraceae family. It is a fairly typical thistle with red to purple flowers and shiny pale green leaves with white veins. Originally a native of Southern Europe through to Asia, it is now found throughout the world.

It has a large number of other common names, such as variegated thistle and marian thistle.

In herbalism, it is used in cases of liver diseases (cirrhosis, jaundice and hepatitis) and gallbladder disease, and is claimed to protect the liver against poisons. An AHRQ study of such claims in 2000 concluded that "clinical efficacy of milk thistle is not clearly established".

Its potent extract is used in medicine under the name silymarin. Another extract, silibinin or a derivative, is used against poisoning by amanitas, such as the Death Cap (Amanita phalloides) and the Fly Agaric (Amanita muscaria).

It has been widely introduced outside its natural range, for example into North America, where it is considered an invasive weed, and New Zealand.

The extract is now also being used in a beverage called Rockstar Energy Drink as an energy enhacing agent.

Hi Shir
Good shot. Great colours, sharpnes, details, DOF and POV. Also gopd Bg and note.
Well done


Hi Shir,
Darn that is a sharp photo, both in quality as in the needles. Excellent POV, DOF color and light. I just like that you can see the spiderweb on the thistle. Maybe just a little more room on the right would be better.

Hello Shir,
Very nice shot! The flower is perfectly placed in a frame, whole picture has lovely, natural colours and is very pleasant to look at. The details are very sharp. I like it!

Hello Shir,
An excellent composition with very nice color, light, and sharp details..
Excellent DOF, isolating the subject from the BG well. I like the added color from the OOF flowers BG also.
Very well done and Thank You!
