The types of Angelica sinensis are:

1. Donggui. It comes from the Eastern Angelica of the Umbelliferae family, also known as Yamatogui, Japanese Angelica, and Yanbian Angelica. Angelica sinensis is used for medicinal purposes in some areas of Northeast China. The local Koreans in Jilin believe that its efficacy is similar to that of angelica sinensis.

2. Angelica sinensis. It is the root of the Umbelliferae plant Angelica sinensis. Introduced from Bulgaria in 1957, this product is different from Angelica sinensis in properties and pharmacological effects. It has adverse reactions that Angelica sinensis does not have and cannot be mixed with Angelica sinensis for medicinal purposes. The root of Angelica sinensis is conical, with an enlarged root head, with more than two root heads, and a horizontal ring pattern.

3. Yunnan wild angelica. The root of Yunnan Angelica of the Apiaceae family. Also known as Tudanggui in Yunnan. Its effect is similar to that of Angelica sinensis, which is used medicinally in some areas of Yunnan. Its roots are conical in shape, have few branches, and have a brown, reddish-brown or black-brown surface. There are stem scars or stem residues at the top, and transverse ring patterns on the root head.

4. Xing'an Angelica dahurica. Roots of Umbrella Angelica dahurica. Also known as the Northeastern Festival. Angelica sinensis has been introduced and misused in Hunan and Sichuan. Its main root is short and has several branch roots. Its surface is brownish-yellow or brownish-yellow, its texture is dry, and its taste is pungent and numb.

5. Purple flower front beard. The root of the purple-flowered front beard of the Umbelliferae family is also called duck-footed seven and wild angelica. Purple flowered bulrush is actually genuine medicinal bulrush. Its main root is irregular cone-shaped, 3-6 cm long and 1.8-2 cm in diameter.

6. Live alone. The root of Angelica sinensis of the Apiaceae family is the authentic medicinal root. The root is slightly cylindrical, with 2-3 or more branches at the lower part. The root head is enlarged, cone-shaped, and has many horizontal wrinkles.

7. Live alone. The only living root of Umbelliferae. In some areas of Jilin, it is also called native angelica, wild angelica, and fresh angelica. Angelica sinensis was once used for medicinal purposes. The head of the Dadu live root is short and thick, with ring patterns on the surface, leaf base marks on the top, and several branch roots below. Longitudinal wrinkles and transverse lenticel-like scars can be seen on the surface, and sometimes brown, sticky resin-like material can be seen oozing out.

Due to the complexity of the plant varieties called Angelica or Angelica sinensis from ancient times to the present, in addition to the chaotic varieties mentioned above, there are more than 20 kinds of plants called Angelica sinensis in the Apiaceae family. There are four or five species called Tudanggui in the family. In addition, the roots of various plants belonging to the Asteraceae, Polygonaceae, and Ranunculaceae families are also called Angelica sinensis in some areas. Faced with such a complicated situation, we should mainly start by mastering the color, smell and taste of authentic Angelica sinensis. Extended information

Five types of people who should be careful about taking Angelica sinensis:

1. Patients who are bleeding should not use it. Women during menstruation and patients with nosebleeds, gum bleeding, gastrointestinal bleeding, etc. should not think that bleeding means "blood deficiency". Although Angelica sinensis has the function of nourishing blood, it has a thick smell, pungent nature, and can easily disturb the blood collaterals. To replenish blood, it can only be used after its bloodline is calm.

2. It is forbidden for those with internal heat. It should not be used whether it is due to excess heat or deficient heat. Angelica sinensis is pungent and warm to help yang. Using it if you are suffering from internal heat is tantamount to "adding fuel to the fire", which is really a taboo.

3. It should not be used by teenagers, children and infants. Children who are growing vigorously are full of vitality and yang energy. Ingesting the hot and powerful Angelica sinensis will not only easily get angry, but may also lead to precocious puberty.

4. Pregnant women should not use it. Angelica sinensis walking away without keeping it can easily cause fetal movement due to fetal heat.

5. It should not be used by patients with cold or fever. Those who feel external evil should avoid taking tonic medicine to avoid leaving enemies behind closed doors.
