Interesting, thanks! The skullcap species used in the study was Scutellaria ocmulgee. It was even an intracranial model (F98 syngeneic rat glioma).
We just reached a homeopatic pharmacy that can provide us of Scutellaria. Not sure which type, anyway is a good component to add. Searching in Amazon, the presentation is around 400mg, not sure if with 2 capsules, dose recommended, we can reach the concenation detailed in the study, will take a look deeper.
