So I have pretty bad allergies this time of year and the only things that seem to help are Zyrtec and Flonase but I’m trying to avoid synthetics. Does anyone know whether the beta sisterol in black seed oil has potent dht inhibiting effects? Beta sisterol has been shown to block dht but it’s also in avocados which are ok on the pfs regimen. It’s interesting how the other herbs and nutrients like quercetin & nettle leaf have dht inhibiting effects. Some kind of correlation between histamine and dht.
