|“|| Satomi: "Do you remember me?"|
Derek: "I remember the tea. You always brought that tea that smelled terrible."
Satomi: "I brought that tea as a gift. Your mother loved it."
Deaton: "What kind of tea? [...] The tea with the smell, what kind was it?"
Satomi: "Reishi. Wild purple reishi. It's very rare."
Deaton: "It's also a very powerful remedy for sickness."
Reishi Mushrooms, also known as lingzhi mushrooms, are a species of mushroom that encompasses several fungal species of the same genus. Many of the species have been used as a medicinal mushroom for over two thousand years in Chinese, Japanese, Korean, and Vietnamese medicine.
Reishi mushrooms have acted as a protective agent and a cure against several supernatural ailments. The first is the infection caused by the ingestion of a Nogitsune fly; after Ken Yukimura was forced to swallow one by the Nogitsune, Noshiko Yukimura had Ken eat some of the mushrooms, allowing him to cough up the fly before it could control him.

The mushrooms were then used again after the Deadpool assassin known as The Chemist released his Modified Canine Distemper Virus, infecting most of Satomi Ito's pack, as well as Scott McCall, Kira Yukimura, and Malia Tate. While Alan Deaton, Derek Hale, and Melissa McCall were searching for a way to save the supernatural creatures who had not yet died from the virus, it was discovered that Satomi never got sick because she was regularly drinking tea made out of the mushrooms, which essentially inoculated her against the virus. A jar of the mushrooms found in the Hale Vault were ultimately used to save Kira, Malia and Scott after the three inhaled the mushroom dust in the jar. ("Weaponized")
- In Japan, reishi mushrooms are known as "the immortality plant."
- In a conversation between Satomi Ito and Derek Hale, it was revealed that Talia Hale was very fond of drinking wild purple reishi tea, which was why Satomi brought it with her whenever she visited Talia so they could drink it together.
- According to Derek, tea made from the reishi mushrooms smells terrible.
