I've heard getting lots of vitamin d can help with skin conditions like that. I'd try a really good dose of d3 every day, like 4000 IU (studies are showing that much is great in pregnancy for all kinds of things, and still far below toxic levels).
I've seen things about turmeric and onion juice on the rash helping soothe it immensely if you don't mind being stained yellow and smelling of curry.
Are you sure it's PUPPS? Typically that doesn't show up until much later in pregnancy. Have you had your liver enzymes checked? Dandelion root has been used by some with success.

I'm pasting below my post from 2005 when I had PUPPP. Hope it helps!
PUPPP is the worst!!!! I am 38.5 weeks pg with twins and started having symptoms at about 35 weeks. This is more than just an itchy belly. It starts with the stretch marks on your belly and then spreads almost everywhere. Not only is it the kind of itching that make you feel like you are losing your mind, but it is an ugly rash. I had little blisters and hives on my arms, legs, tops of feet and hands, hips, butt...it sucked! Over the counter steroid cream was useless, and Benadryl helped me sleep a bit, but did nothing for the rash. Oatmeal baths were useless. I have, however, been completely cured. This may not work for everyone, but it did for me!
1. On the advice of my midwife I took Dandelion Root extract tincture. This seems to have variable results, but my midwife put me on a huge loading dose and I think this made a difference. I took a half a dropperful every hour for the first day, four times a day on the second day and went to twice a day by the third day. She said I would see results within 48 hours and sure enough, I started to get some relief right at 48 hours and within 5 days I was totally better.
2. She also recommended I take Milk Thistle and Choline. I am blanking on the doses she recommended, but I took less...I am wary of taking anything in pg, esp. starting a bunch of new stuff at once. I ended up taking 350 mg of the Choline and 300 mg of the Milk Thistle twice a day. All these herbals are liver tonics.
3. On the advice of another MDC mom (Thanks Shannon0218!!) I had dh paint my body in a water and cornstarch paste with just a few drops of tea tree oil. I left it on for 30 minutes. I think this really paved the way for the rash to start drying out.
I don't know what, if any of these measures worked. I have read in at least one place that the first week is the worst and that the symptoms can resolve on their own, but most of what I have read indicates that delivery is the only real cure. I feel soo lucky to not have PUPPP anymore. It was like torture. People are induced early because of PUPPP or put on high doses of systemic steroids.
For symptom relief I also found that ice packs were really helpful. I would put them in the worst spots instead of scratching.
