I am dermatologist that has a strong interest in the natural treatment of psoriasis. I hope I can help give some perspective on lifestyle interventions that actually have some basis in science behind them.
Chel, dermatologist chiming in here. The key that I teach my patients is to slowly decrease the use of your creams only once it is clear. Then go to once per day for a week, then once every other day for a week etc. Sometimes, you will find that you might need to use on the weekends to keep it under control or every 3rd day but the key is to figure out the least amount of use to keep your skin under control. During this time there are other non-steroidal creams that could be introduced to decrease that use even further.
For people who have issues with nightshades, the main issue is set of chemicals in the skin and seeds. For those people who are sensitive, you can eat tomatoes and peppers if they are de-skinned and de-seeded with no problems at all. Traditional tomato sauce from Italy by the way is always de-skinned and de-seeded, they probably knew about this issue a long time ago.
@sarah - when it comes to magnesium - you want to take several different types as everyone absorbs them differently. I don't know of any studies that show low magnesium making psoriasis worse but since most of the population is not getting enough, it's certainly not going to hurt and is part of supplementation that starts with getting your Vit D in range, which is associated with lower rates of psoriasis. Now, personally, I try to soak in epsom salt baths a few times a week as that can allow you to absorb some of the magnesium through your skin. I also take various forms of magnesium. I take mag threonate in the mornings and also alternate at night malate vs a combo mag. They can cause diarrhea so you have to see how your tolerate and you can lower or increase as tolerated. I think it is important for overall health and if you are supplementing with Vit D/K. PM me if you want more information about this.
I get this question from my patients also. Basically, the main thing you need to know is that Vitamin D/K2 and Magnesium all interact and need each other in the body. By supplementing too much with Vitamin D and ignoring K1/K2 and magnesium your system won't be balanced. Some companies like lifeextension have d3/k2 in combination in ratio's that make sense. Magnesium which most people are deficient in another topic altogether but one I would be happy to comment on if others are interested.
@ava - no I don't have psoriasis. In 2004, I had a life-threatening diagnosis - and started learning about natural treatments - then the same year, I had a patient cure herself of severe lupus, which made me look at the literature for auto-immune diseases. Then from all that I learned, I started introducing this to my psoriasis patients and continue to refine my suggestions.
@ava I use narrowband UVB for a lot of my patients, I find it works well and has less risk from a skin cancer perspective that PUVA. The wavelengths of light have been studied and a narrowband of UVB works best so if done properly - it can work very well. Combine that with the natural plan that I put my patients on and it is winning combination for the majority of patients, especially if they are open to lifestyle changes.
Michelle, high doses of turmeric usually from supplements can lower blood pressure and can also interact with blood thinners so if you are on blood pressure meds or blood thinners best to talk to your doctor about that before starting supplements. I doubt a glass of golden milk however will make much of a difference. I don't recommend it topically, stains everything and I mean everything! :)
