Crude drugs expected to have an estrogenic effect were screened for their inhibitory activity on testosterone 5α-reductase. Testosterone 5α-reductase is an enzyme catalyzing the conversion of testosterone to dihydrotestosterone, which possesses high affinity for the androgen receptor. Among the crude drugs tested, we focused on Puerariae Flos (the flowers of Pueraria thomsonii) due to its potent inhibitory activity and suitability for commercial use. The 50% ethanolic extract of Puerariae Flos (PF-ext) showed inhibitory activity of 60.2% at 500 μg/ml against testosterone 5α-reductase. Interestingly, it was more potent than that of Puerariae Radix (roots of Pueraria lobata). PF-ext also showed in vivo anti-androgenic activity using a hair growth assay in testosterone-sensitive male C57Black/6NCrSlc strain mice. We demonstrated saponins, including soyasaponin I and kaikasaponin III, to be active components in PF-ext. In addition, hair growth promotion activity in C3H/He mice at 2 mg/mouse/day of the topical administration of PF-ext was demonstrated. Thus, Puerariae Flos is a promising crude drug for treating androgenic alopecia.

Why is this cool?

 This may be the paper that leads to the cure to baldness!! Men have dreamed of this for untold millennia! My favorite time of year is winter because it gets cold enough here that I have to wear a hat. While capped, I enjoy looking at my reflection in windows because I look like I have hair. I feel comfortable and confident with the slightest illusion of HAIR!!

 Before we get too far, let's discuss the paper. It says that they tested "crude drugs" ( I don't know exactly what this means) for their ability to inhibit 5-alpha reductase. One of the crude drugs that they tested was the extract of the flowers of Pueraria thomsonii.

They found stellar inhibition and, when tested on mice that were genetically engineered to be bald, they found that there was HAIR GROWTH!! One of the interesting things is that they don't identify the exact compound that inhibits 5-alpha reductase activity, but they have some leads in saponins. More on that when I review the entire paper.

 Often I find myself jumping to what I think is the natural conclusion of an idea and right now that conclusion is the end of "old." When you think of old men, you have several thoughts:

1. Baldness

2. That remaining hair is gray

3. Weathered skin

 Science will have cured baldness! Lotion and lack of outdoor manual labor has done in weathered skin! Normal hair dye has masked grayness! What is the new old? Kevin Bacon. He is 53 years old and is kicking it like he was in Footloose!! Our ideas of masculine old men will have to adjust to the Bacon paradigm!!
