Sang Shen
Also known as: Morus alba fruit, mulberry fruit.
Sang Shen remains in the ingredient set because the site preserves the nourishing fruit branch of the TCM protocol, but the evidence is too indirect to treat it as anything other than an optional Tier 4 layer.
Where this fits in the system
What it does
Sang Shen is a gentle support option for recovery that feels dry, depleted, and somewhat frayed. It belongs in the nourishing TCM branch only.
How it works
Where it fits
This herb is best matched to the softer, drained version of recovery rather than the acutely toxic version. That is why it appears in Nightcap, Debrief, and Mayday rather than earlier.
Buying guidance
A simple mulberry-fruit tea or TCM product is sufficient. Treat it as a supportive adjunct and keep the core recovery stack in front.

Why it is Tier 4
The page exists because the long-tail library is meant to stay complete. The evidence level keeps it clearly in the optional bucket.
