I'm not a doctor, but personally,  I'm quite sure Cora didn't use Dreamshade to kill Eva. Watching the episode The Queen Is Dead  once again I noticed that Eva vomited small amounts of blood.

Dreamshade kills differently. All victims of dreamshade have in common that - wherever the wound is - black veins spread around it (Liam cut his arm (Good Form), an arrow nicked David). In time the black veins spread further. When they reach the heart the victim dies of cardiac arrest. The creators gave us the opportunity to watch the effects of dreamshade twice. Neither David (Good Form) nor Mr. Gold (The Miller's Daughter)  vomited blood. They both felt feeble and weak, having difficulties to bring up even enough strength to keep up with the rest of their company. Dreamshade affects the heart of its victims. Hook thrusted his hook into Gold's chest that's why Mr. Gold had a bloody cloth when Emma visited him. Thrusting a hook into someone's chest itself causes a deep wound, he was trying to stop the bleeding.

Neverland is a land of magic. Magic is a  natural part of Neverland. The plant Dreamshade is native to Neverland. In my opinion, Dreamshade itself is not magicial. I'd rather say Dreamshade adjusted to the environmental conditions of the island. Comparable with a cactus, which is able to grow in deserts because it managed to adjust to heat and shortage of water, Dreamshade adjusted to the environmental conditions of Neverland. In countless years of evolution Dreamshade learned to tolerate Neverland's environmental conditions. The plant learned to tolerate magic. Maybe Dreamshade even requires magic to grow.

I don't know when or where Jared said that Cora used magic to poison Eva.

One of the basic rules of magic is that magic cannot bring back the dead, unless you trade one life for another. Neal had to die in order to resurrect his father. (Quiet Minds). It's also known that light magic can undo dark magic (e.g. There's No Place Like Home: The Blue Fairy transforming Snow White back into human form after Snow used dark fairy dust (= dark magic) on herself and had transformed into a lady bug.) Of course in order to undo a curse with light magic the victim of the curse still has to be alive.

In the Land Without Magic vomiting blood might have various causes. Poisoning is only one of them. Before Cora revealed to us that she poisoned Eva my first thought was, Eva might have fallen ill with tuberculosis.

It's possible that Eva was poisoned by magic. However, no spell known to me causes the victim to vomit blood. All I can say is, that for the reasons I listed above I don't think it was Dreamshade that poisoned Eva. I'm not familiar with the flora of the different worlds we've visited so far. There might be countless ways to poison someone without using magic and even more if you use magic. Probably, we'll never know for sure.
