The motives of Cordyceps sinensis and sea cucumber are mainly psychological. At most, it is nourishing, improving immunity and supplementing physical fitness. I used to have kidney deficiency and no energy. I also ate various tonics, and the effect was not obvious. Now I also drink Jinfang tea to supplement kidney essence. Kidney essence is abundant every day, unlike before when I was sleepy during the day. After the kidney essence is sufficient, the mind is clear and the efficiency of doing things during the day is higher.
