Medicinal Uses:
Bupleurum has been used in traditional Chinese Medicine for at least 2,000 years and is famously used in the traditional "chai hu" for treatment of coughs, fevers, and influenza. The roots are harvested in the autumn and can be used fresh or dried. A paste of the plant is applied to boils.
It is the primary herb in dozens of classical formulations and a key ingredient in the formula known as sho-saiko-to, making up 16% of the formula. It is also a Japanese kampo or traditional herbal medicine formula based on the traditional Chinese formula xiao-chai-hu-tang. In English, it has been called minor bupleurum formula.
 
I urge anyone buying seed to do their homework on germination, I have not raised and cannot raise many of these plants as I am sub-tropics here in St Augustine, Florida. All seed are NOT alike!  There are so many different factors in germination and not doing a search is throwing your money away. I want everyone to be successful when growing your flowers from seed it is the most rewarding experience in Gardening and you can do it, if you give the seed what it needs to grow. I always check 3 sites of info to choose how I will go about it. It is not hard to do, if you do it right!
SEED GERMINATION TIP!!!!!!!
ONLY GERMINATE A SMALL PORTION AT A TIME.
DON'T PUT ALL YOUR MONKEYS IN A BARREL.
Good Luck and Happy Planting!!!!
