[2] In May 2024, director Damien Neva in collaboration with Roadburn Festival released a documentary titled Six Hours 42 Minutes with Sumac.

[4] To support The Healer, Sumac will tour North America in June and July 2024 starting with a set at the Vancouver International Jazz Festival.

[6] Patric Fallon of Pitchfork praised the album within Sumac's discography, stating: "If Love in Shadow searched ever more deeply for metal's untapped possibilities and May You Be Held confidently wrestled with its roiling unknown, then The Healer swallows its universe whole and reforms it anew.

"[6] Writing for PopMatters, Seth Troyer drew similar comparisons to the bands catalog, stating: "It feels like the culmination of a sort of trilogy for Sumac that began with 2018's Love In Shadow and continued with the equally stunning May You Be Held in 2020.

"[7] Writing for AllMusic, Paul Simpson said: "The Healer is an emotionally draining experience, like all of Sumac's other releases, but it reaches transcendence in a unique and powerful way.
