Genestra Brands Phyto-Gen Perid-gen Review

This is a liquid plant bud and young shoot remedy with three extracts at 0.09 milliliters each. The human studies behind the oak ingredient tested French oak wood extract at 300 milligrams a day, not oak bud extract, and the liquid dose here cannot be compared to that amount. In those wood extract studies, people with high oxidative stress had less cell damage, better mood, less fatigue and better sleep after 8 weeks ^[1]. People with chronic fatigue had lower free radicals after 4 weeks ^[2], and people with temporary liver problems had lower free radicals and inflammation after 12 weeks ^[3]. Women recovering from hysterectomy had less oxidative stress at 4 weeks, though both groups had improved by 8 weeks ^[4]. Amateur triathletes had less free radical buildup after exercise ^[5][6]. None of this measured biological age, and none of it tested oak buds. Dog rose has only animal studies, such as mice keeping more muscle during immobilization ^[7] and rats with less kidney oxidative stress ^[8]; no person has been studied. Cedar of Lebanon has no studies at all. Animal and cell studies are never counted.
