Only Mages can use the lyrium. When you have Morrigan, you can help replenish her magic/mana in combat when she runs low (it is the blue column on her portrait.) You have to switch to her using your RB/LB buttons and then open the radial menu with LT and select the lyrium potion which she can then use.

Poisons, etc, can only be used by rouges in combat or to make traps (if they have the trap-making skill.) Health potions and injury ones can be used by any party member to fix their injuries or replenish their health.How do I use Lyruim potions in Dragon Age: Origins?
