could consider a gift basket with easy at-home/stress-reducing/good-for-you things - magnesium is emphasized below, because stress increases mag excretion, and lower mag in turn increases stress, which results in more magnesium excretion, in an unfortunate downward spiral.
so. i just today noticed free samples available from this web site
http://naturalvitality.com/natural-calm/ (don't know if there are limitations re where they will ship however).
also, epsom salts (or similar) baths can help deliver stress-relieving essential nutrients known to be lower in ms patients:

if she likes homemade treats, you can identify any foods she likes which contain ingredients from this list, maybe a snack or light meal recipe prepared for her could be appreciated. one thing which i personally am going to try out in the near future will be magnesium dense energy balls (they'll be great for other essential nutrients as well, of course). reviewing the magnesium foods list, such a snack could include oats, pumpkin seeds, sesame seeds, chopped cashews, sunflower seeds, chopped almonds, maybe some dried papaya (i'll use gojis and cranberries in part for personal preference - also gojis are not listed on the whfoods website but are reportedly much higher in magnesium, closer to 150mg/100g), flaxseeds, and not because it's from this list but just because i know it's good for magnesium, some dark chocolate (146mg mag per 100g - it's the sugar that's the dealbreaker there though)

and beyond that just because i am also interested in selenium, i'll add chopped brazil nuts to the mix.
i will be considering things like honey, maple syrup and or peanut butter to hold these together once i have all the ingredients on hand, maybe roll individual ones in coconut. being me, i will likely work out how much food mag goes into the total recipe, then based on how many balls it makes, i will know how many mgs of magnesium have been delivered in each. and then i would use them sparingly, knowing that they'd be on the high calorie end of the healthy mag foods scale (note all sources considered 'excellent' on this healthy foods site, are dark leafy green veggies)

if she wold appreciate a meal made so she can just heat something up, maybe a nice recipe high in stress reducing minerals. i have not tried this recipe, but i do consider spinach feta pie a superior dish for delivering stress-relieving nutrition.
