Hi, I'm a chemist with a Master's Degree in Chemistry. I delivered a seminar about the nature and treatment of psoriasis in college so I'm very familiar with it. It's a very rare disease caused by abnormality of the pigment in blood. The blood cells (hemoglobin) mostly has a malfunctioned heme, the pigment that is responsible for the color red in blood (molecular structure is somewhat similar to that of chlorophyll which makes leaves of the plant green), So people with this kind of disease are very pale and are very sensitive with sunlight to the extent that their skin would have abrasions/wounds due to sun exposure. I don't know the extent of her case though. It's mostly genetic.
I know the treatment options for her and I'm very much willing to ask medical experts to validate it. I also have an access to online scientific journals to research on the latest breakthrough on the treatment of this kind of disease. I can work for 30 days or more just to walk her through to all the process available for her to get the necessary treatment. Although I'm not someone from India, I can always use tools available in the web to look for the help she needs
