Bupleurum is mainly used in Chinese medicine. It's commonly employed in herbal formulas as it's thought to direct the flow of Qi in the target organ. This target organ is determined by the other herbs in the formula.
Bupleurum has been the subject of study for its antiviral actions with strong indications of efficacy in that area so far. Several components of this herb have been found to inhibit a variety of virus' including HIV, parainfluenza, and poliovirus.
The other main action of this herb is directed at the liver and kidneys.

Bupleurum root is one of the most important herbs used in Chinese herbalism. It is used to relieve liver tension and digestive disturbances. It is detoxificating and antimicrobial as well. .
Bupleurum is often combined with other herbs to clear stagnation anywhere in the body. It is used to relieve muscle spasms, lumps, and bleeding due to heat, and menstrual irregularities. .
The essential oil of Bupleurum root is used to relieve surface heat. .
This herb is rarely used alone, but is very common in combinations. It is usually added to improve the detoxification of a target organ, and regulate the flow of Qi through the body. .
Bupleurum is commonly used in traditional Chinese medicine to detoxify various target organs (depending on the other herbs in combination), relieve liver tension, and regulate the flow of Qi throughout the body .
There are over 3500 species in the Apiaceae family, 300 of which are medicinally active . In the Bupleurum genera, there are about 180-190 species .
Bupleurum marginatum, and many of the other Bupleurums are perennial herbs, grow up to 60 cm in height, and have oblanceolate leaves .
Habitat Ecology, and Distribution:
Still compiling research.
Harvesting Collection, and Preparation:
Mainly cultivated in Hebei, Henan, Liaoning, Shananxi, and Gansu provinces of China, and collected in the spring or autumn .
The root is generally sun-dried and sliced. It can be used raw this way, or fried in wine or vinegar. .

Pharmacology and Medical Research:
Bupleurum marginatum extracts were shown to be active against gram-positive bacteria, and less active against fungi and gram-negative bacteria .
Bupleurum marginatum extracts were found to possess antiviral activity which has been suggested to be due mainly to the saikosaponin content . This action has been confirmed in studies investigating the effects of saikosaponins on various virus' which suggest this action in other species of Bupleurum as well [13-15]. The lignans and flavonoid aglycones are also suggested to provide some antiviral support .
The lignans were found to exert antiviral action through tubulin binding, reverse transcriptase, and topoisomerase inhibition [16, 17].
Some of the flavonoids present in bupleurum metabolise into phenolate ions within the body, where they then inhibit viral polymerase activity, and bind with viral nucleic acid or viral caspid proteins. This leads to an inhibition or reduction in viral replication. . The flavonoids quercetin, and rutin (and likely other flavonoids), have been found to be active against such viruses as HSV-1, HIV-1, HIV-2, poliovirus type 1, parainfluenza virus, and respiratory syncytial virus .
Bupleurum was shown active against several in vitro cancer cell lines, which was suggested to be due mainly to the saikosaponin content .
The lignans and flavonoids are also suggested to possess cytotoxic and apoptotic actions in human cancer cell lines .
Known allergies to other members of the Apiaceae family
May cause flatulence, bloating, nausea, vomiting, sedative effects, or reflux in large doses or in sensitive individuals .
