There are a number of Alchemical items, such as Burn Butter, Cooling Gel and Gash Glue that would seem appropriate. But, since I don't know the price of that kit off hand, I can't say that they'd fit in the budget.
The Conan Healing Kit goes for 50 sp, but it's hard to convert D&D to Conan because in the Conan RPG, gold is very, very valuable. Silver is used for 99.99% of all items. For example, a broadsword in Conan costs 125 sp. A dagger costs 3 sp. A heavy mace costs 3 sp. A javelin is 3 sp. A sling is 1 sp. A shortsword or a cutlass is 50 sp.
Where'd you find that other stuff. I don't think it's got a counterpart in Conan.
