Wands of healing were never a problem they were part of the game in 3e, they were how you kept going. In 5e, between hit dice expenditures during short rests, every group I have seen having a bard for the most part so using Song of Rest to augment that, and two of the four groups I am in have someone with the Healer feat, I see no need for wands.
At the end of a short rest everyone is at full HP or close to it, for the encounters in between those short rests you have spells and potions. Potions can be crafted by anyone with herbalism kit proficiency and spells like healing word bring you up from 0 h.p to positive with a bonus action and the only down side is you are prone at the start of your turn.
