The extract mentioned is from the following species:

[known as: Japanese red pine, the Japanese pine, or Korean red pine]
EDIT 2:
The bark of the same species contains neuroprotective compounds:

“Taken together, these results suggest that [Korean red pine bark extract] and its constituent antioxidative phenolics are potent neuroprotective agents that can maintain cell viability under oxidative stress and inhibit cholinesterase activity.”
Pinus densiflora Siebold et Zuccarini is also known as the Japanese red pine. Recognizing it is by its red-orange bark and its fascicle (bundle) consisting of 2 long needles. The White pine is also very beneficial for preventing cancer and has been shown to cure autism. Recognizing the white pine is by looking for it having a bundle (fascicle) consisting of 5 long needles. Be careful of other pine trees and evergreens. Many are toxic like the Yew, Norfolk Island Pine, and Ponderosa Pines (Western Yellow Ponderosa Pine, Bull Pine, or Black Jack Pine).
Thanks. I added the Wikipedia link with a brief description.👆
There are toxic evergreens. I didn't find info on the Japanese Red Pine for its toxicity though. It sounds like its safe, but I'm not absolutely sure.
