Does anyone remember this manga

I remember the Mc is a male who is a healer. I think he is a reincarnator. I remember a scene where he goes to the guild to learn to fight. He pays for the lessons by healing adventurers for free. The healers in this world are a bit evil and charge a ton of money. The often won’t heal beastmen. There is one scene where it’s right after his first lesson that a team goes to him for healing and the girl is a beastmen. The express disbelief that he healed her. I remember that a cook who I think is a bear beastmen makes him a drink he calls substance X. It’s for rookies it’s a terrible black mud like drink
