Beta sitosterol does inhibit 5-AR, but the content in peony is too low for your reference to specify it, so the effective peony dose would be impractical, and perhaps dangerous if it caused an overdose of the major components.

Oh really, then prove it!


Beta-Sitosterol: 5-alpha reductase inhibitor, reduces cholesterol (LDL)

Beta-sitosterol is a phytosterols (plant sterol) with chemical structure similar to that of cholesterol. Beta sitosterol inhibits cholesterol absorption in the intestine.[1] It can be found in many plants such as Nigella sativa, pecans, Saw palmetto (Serenoa repens), etc. Beta sitosterol is incorporated in margarine, yogurt, or other foods [9].
What are the benefits of beta sitosterol?

Beta-sitosterol is commonly used for treating benign prostatic hyperplasia [2,3] and high-cholesterol [4].
In bodybuilding world Beta-sitosterol is used in many testosterone enhancers due to its possible effect in 5-alpha reductase inhibition [3,5]. As testosterone levels increase so does dihydrotestosterone (DHT – more active form). DHT is generated by a 5-alpha reduction of testosterone [6]. DHT is the primary contributing factor in male pattern baldness [7].
Prager N. et al. [8] have shown the effectiveness of Saw palmetto (Serenoa repens) and beta-sitosterol, as naturally occurring 5-alpha reductase (5AR) inhibitor, against male pattern baldness (androgenetic alopecia). This pilot study showed highly positive effects. 60% of the subjects treated were rated as improved after final check.
