Just some anecdotal evidence, members of my guild were playing around with it when we first discovered it, and we often got the Potion of Speed (500 Haste for 15 seconds) effect. Some people got the Dreamless Sleep effect, and others got a Destruction Potion effect.

Unfortunately, that's all it did before - give a random potion effect. Now that this returns mana and health, I'll be happy to be carrying these around again.

Below 80% health, you are given the Nightmare Slumber buff (1800 Health/Mana every 2 seconds for 6 seconds, 3 ticks, modified by Alchemist's Stone). The slumber effect is broken by any damage taken.

In combat, and above 50% health, you are given the Haste effect. Between 20% and 50% health, you receive a Healing effect identically to a Runic Healing Potion (2700 to 4500 random heal).

Below 20% health and in combat, you receive the same Healing effect as above, plus a Speed buff (identical to Swiftness Potion), movement speed increased by 50% for 15 seconds.
