Excellent!Wonderful product for overall balance and calm plus the additional help to keep away or fade gray hair. I only take two per day so have extra doses. Make sure you always use Hu Shou Wu instead of fo-ti to avoid any kidney issues or stomach disturbance. Fo-ti is shou wu not cooked down. This is the real thing and best for hair and general well being so may cost little more but safer with correct benefits.
Disclaimer: I took these to support my body while dealing with the consequences of a burnout, and my kidney energy was very low (both yin&yang) so my sensitivity to the formula was probably much higher than a regular healthy person taking these for an added boost or competitive edge. And I can tell this formula is very helpful at boosting kidney yang and suppporting blood circulation and heart strengh, the only caveat is if you are yin deficient as i was, you need to be very careful as the formula will produce heat and needs to be counter-balanced (in my experience) with either pregnenolone or Liu Wei Di Huang, like say you take it once a day at lunch to survive a busy aternoon at work and then to cool down your body you would take LWDH at dinner with or without added pregnenolone. So yeah, great product, very helpful to tonify the body and make it more resilient !
I studied Chinese Herbology many years ago. HoShouWu is one of the famous 'chi' herbs, recommended for overall health. Chinese herbs are more effective in combinations compared to taking a single herb. I like that Teeguarden has included several traditional 'assistant' herbs to make the HoShouWu more effective.
Shou Wu Formulation might seem like one of the "side purchases" as opposed to a good reishi, ginseng, etc but it's often the side formulas which fill in the blanks in your overall vitality. Along with adaptogen energizer and the astragalus advanced, this is one of the 3 which when I stop taking it I'm not as vital, productive, happy all the time, winning all the time. All these herbs effect our drive and will as well as our immune system on a subtle level. I've been taking them for almost 20 years now and can say for sure it's dramatically upgraded my life in every area.
