The text discusses the effects of Horny Goat Weed, Damiana, Muira Puama, and Cannabis on PDE5 inhibition and endothelial function.

Infact verdict: Mostly True (62/100).

The claims regarding the effects of Horny Goat Weed, Damiana, Muira Puama, and Cannabis on PDE5 inhibition and endothelial function have varying levels of support from the evidence. Horny Goat Weed is supported by multiple sources indicating its PDE5 inhibition and nitric oxide enhancement. Damiana lacks specific evidence for the claimed effects on NO release and PDE5 expression. Muira Puama shows evidence for upregulating iNOS and sGC but lacks direct evidence for PDE5 downregulation. Cannabis has mixed evidence regarding its vasodilation effects through CB1/CB2 receptors, with some disagreement on mechanisms. Overall, the claims are partially supported, with some lacking direct evidence for specific assertions.

Mixed Health
Damiana upregulates endothelial NO release to 115% of control values and downregulates PDE5 expression.
The evidence does not provide specific figures or confirm the exact effects of Damiana on NO release or PDE5 expression. The claim lacks direct support from authoritative sources.

Muira Puama upregulates eNOS and iNOS up to 15-fold and elevates soluble guanylate cyclase 42-fold.
Evidence supports the claim that Muira Puama upregulates iNOS and elevates sGC significantly, but the specific figures are based on studies involving combinations with other compounds.

Muira Puama boosts cGMP by 85% and downregulates PDE5.
While there is evidence for cGMP upregulation, there is no direct evidence for PDE5 downregulation by Muira Puama. The claim is partially supported but lacks full verification.

Cannabis promotes microvascular hyperemic vasodilation via vascular CB1/CB2 and endothelial signaling.
There is evidence supporting the role of cannabinoids in vasodilation through CB1 and CB2 receptors, but the exact mechanisms are not fully agreed upon. The claim is partially supported by the evidence.
