Sister Kate and Sister Darcey call themselves the “Sisters of the Valley,” and they’re on a unique spiritual journey to change the world one cannabis plant at a time.

The two women “consider themselves nuns, but are not Catholic, or traditionally religious,” news station ABC 7 reported.

“The sisters are not members of a religious order but they say they are on a spiritual quest to heal the sick with their cannabis cures.”

“We spend no time on bended knee, but when we make our medicine it’s a prayerful environment—it’s a prayerful time,” Sister Kate told reporters.

Sister Kate and her apprentice Sister Darcey run a small marijuana grow operation in the garage of their shared home in Merced, California.

The plants they grow are designed specifically to produce high levels of CBDs—the chemical component of cannabis that helps treat a number of health issues—and little to no THC—the primary psychoactive ingredient in marijuana.

Although their plants won’t get anybody high, the two women use the herb they grow to produce a number of medicinal products, which they sell on Etsy under the name “Sisters of the Valley Pain Management Center.”

“We make CBD oil which takes away seizures, and a million other things,” said Sister Kate. “And we make a salve, that’s a multi purpose salve, and we found out that it cures migraines, hangovers, earaches, diaper rash, tooth aches.”

The sisters’ healing work is now being threatened, however, as the Merced City Council is considering a ban on all marijuana cultivation.

“Yes it’s frustrating to me because there are all of these people with negative attitudes about something that is truly God’s gift,” Sister Darcey said about the proposed rule.

The city council is set to vote on the issue next week, and until then, Sister Darcey, Sister Kate, and other pot activists are on a mission to keep marijuana as accessible as possible in their city. “Embrace, regulate and tax, that’s all we want them to do,” said Sister Kate.
