[RPG] Can the warforged from UA: Eberron benefit from healing spells and the Medicine skill

Funnily enough, works by RAW.

There is no prohibition of magical healing in construct traits, though some constructs are explicitly immune to magic except select few effects.

There is also no prohibition in the heal spell.

Technically, you can do it, but expect a heavy book thrown by your DM. He will also probably houserule it away, at least I personally would.

Note:

Can't remember anything on that in 3.5 either, though the description of Warforged contrasts the possibility of both special and positive-energy healing (emphasis mine):

As living constructs, warforged can be affected by spells that target living creatures as well as by those that target constructs. Damage dealt to a warforged can be healed by a cure light wounds spell or a repair light damage spell, for example, and a warforged is vulnerable to disable construct and harm. However, spells from the healing subschool and supernatural abilities that cure hit point damage or ability damage provide only half their normal effect to a warforged.

That leads one to the implication of impossibility of positive-energy based healing for a regular construct, even if it is not stated anywhere.

As of 5e's published release and the Unearthed Arcana article, Warforged are treated no differently than PCs of other races.

Since it does not mention any healing exceptions for warforged in the Unearthed Arcana article that introduces them to 5e; they should have any and all healing effects work on them as per usual.

2018 update (thanks @Trevel)

This question has now been explicitly answered in the Wayfinder's Guide to Eberron, under the description of the warforged's composition (p. 67):

While they’re formed from stone and steel, warforged are living humanoids. Resting, healing magic, and the Medicine skill all provide the same benefits to warforged that they do to other humanoids.
