In vivo anti-tumor effect of berberine in human colorectal adenocarcinoma (LoVo)[1]
The in vivo antitumor efficacy of berberine was examined using human colorectal adenocarcinoma LoVo xenografts in a nude mouse model; 1 × 107 cells were implanted subcutaneous injection (s.c.) in the flanks of 5-week-old BALB/c nu/nu mice. After the tumors were grown up to about 1,000–1,500 mm3, the mice were sacrificed and the tumors were divided into equal fragments. Fragments (6–8 mm3) of colorectal adenocarcinoma were implanted s.c. in the flanks of 5-week-old BALB/c nu/nu mice. Tumors were allowed to develop for 2 weeks. Once tumors were established, the mice were divided randomly into five groups. The berberine-treated groups (ten mice each group) received 10, 30, or 50 mg kg−1 day−1 berberine by gastrointestinal gavage for 10 consecutive days. The 5-FU-treated group (10 mice) was given 30 mg kg−1 day−1 by intraperitoneal injection for 10 consecutive days. The control group (11 mice) was given sterile water. Measurements of body weights and tumor volumes were recorded every 1–3 days until the experimental endpoint, at which the tumors were debilitating to the mice. The long axis (L) and the short axis (S) were measured, and the tumor volume (V) was calculated using the following equation: V = S × S × L/2. Once the final measurement was taken, the mice were sacrificed by cervical dislocation. The inhibitory rates were determined by comparing the volume of the control group and the treatment group: (1 − V treatment/Vcontrol).

Effect of the combination of berberine and 5-FU on the growth of human colorectal adenocarcinoma (HT-29) xenografts in nude mice[1]
The in vivo antitumor efficacy of the combination of berberine and 5-FU was examined using human colorectal adenocarcinoma HT-29 xenografts in a nude mouse model; 1 × 107 cells were implanted subcutaneous injection (s.c.) in the flanks of 5-week-old BALB/c nu/nu mice. After the tumors were grown up to about 1,000–1,500 mm3, the mice were sacrificed and the tumors were divided into equal fragments. Fragments (6–8 mm3) of colorectal adenocarcinoma were implanted s.c. in the flanks of 5-week-old BALB/c nu/nu mice. Tumors were allowed to develop for 3 weeks. Once tumors were established, the mice were divided randomly into four groups. The berberine-treated group (ten mice) received 50 mg kg−1 day−1 berberine by gastrointestinal gavage for 10 consecutive days. The 5-FU-treated group (10 mice) was given 30 mg kg−1 day−1 by intraperitoneal injection for 10 consecutive days. The combination group (10 mice) was given berberine and 5-FU. The control group (10 mice) was given sterile water. Measurements of body weights and tumor volumes were recorded every 3–4 days until the experimental endpoint, at which the tumors were debilitating to the mice. The long axis (L) and the short axis (S) were measured, and the tumor volume (V) was calculated using the following equation: V = S × S × L/2. Once the final measurement was taken, the mice were sacrificed by cervical dislocation. The inhibitory rates were determined by comparing the volume of the control group and the treatment group: (1 − V treatment/V control).

Hepatotoxicity
Berberine has not been linked to serum enzyme elevations during therapy, although there have been few prospective studies in humans that have reported on its effects on laboratory test results in any detail. In published trials, berberine has appeared to be well tolerated with only minor and few adverse effects which have been similar in frequency among persons receiving placebo. Despite wide scale use as an herbal supplement, berberine has not been linked to published instances of clinically apparent liver injury. The frequency of hypersensitivity reactions to berberine is also not known.
Likelihood score: E (unlikely cause of clinically apparent liver injury).
Other Names: Goldenseal, Oregon grape, Tree turmeric.
Drug Class: Herbal and Dietary Supplements

Effects During Pregnancy and Lactation
◈ What is berberine?
Berberine is an ingredient found in many plant species, including goldthread, huang lian, Oregon grape, and barberry. It has been used to treat many conditions, such as diarrhea, diabetes, and high cholesterol. It has also been used for weight loss.Berberine is available as a supplement sold over the counter. In general, it is suggested to speak with your healthcare provider before taking any supplements. Many supplements are not recommended for use during pregnancy unless your healthcare provider has prescribed them to treat a medical condition. This is because they are not well-regulated or studied for use in pregnancy. For more detail on supplements, please see the fact sheet at https://mothertobaby.org/fact-sheets/herbal-products-pregnancy/.
◈ I take berberine. Can it make it harder for me to get pregnant?
It is not known if berberine can make it harder to get pregnant. There is some information to suggest berberine can increase fertility and pregnancy rates in females with polycystic ovary syndrome (PCOS).
◈ Does taking berberine increase the chance of miscarriage?
Miscarriage is common and can occur in any pregnancy for many different reasons. It is not known if berberine increases the chance for miscarriage. One study suggests that berberine may cause uterine contractions and miscarriage. However, information is very limited. As there can be many causes of miscarriage, it is hard to know if an exposure, the medical condition, or other factors are the cause of a miscarriage.
◈ Does taking berberine increase the chance of birth defects?
Every pregnancy starts out with a 3-5% chance of having a birth defect. This is called the background risk. One report looking at 218 pregnancies exposed to huang lian (which contains berberine) did not show an increased chance of birth defects above the background chance.
◈ Does taking berberine in pregnancy increase the chance of other pregnancy-related problems?
Studies have not been done to see if berberine increases the chance for pregnancy-related problems such as preterm delivery (birth before week 37) or low birth weight (weighing less than 5 pounds, 8 ounces [2500 grams] at birth).Berberine can change how bilirubin (a yellowish pigment that is made during the breakdown of red blood cells) binds to serum albumin (the main protein in blood plasma). This can cause a buildup of bilirubin in the brain, which can lead to brain damage and other issues. While information on this is very limited, one author suggests avoiding herbs and products that contain berberine during pregnancy.
◈ Does taking berberine in pregnancy affect future behavior or learning for the child?
Studies have not been done to see if berberine can cause behavior or learning issues for the child.
◈ Breastfeeding while taking berberine:
Berberine passes into breastmilk, but how much berberine gets into breastmilk is not known.. It is possible that berberine in breastmilk could cause a buildup of bilirubin in the infant brain, which can result in brain damage and other issues. This makes berberine exposure via breastmilk a concern, especially in newborns. Also, because berberine is a supplement, it is not recommended for use during breastfeeding unless your healthcare provider has prescribed it to treat a medical condition. Be sure to talk to your healthcare provider about all your breastfeeding questions.
◈ If a male takes berberine, could it affect fertility (ability to get partner pregnant) or increase the chance of birth defects?
Studies have not been done in humans to see if berberine could affect male fertility or increase the chance of birth defects above the background risk. In general, exposures that fathers or sperm donors have are unlikely to increase risks to a pregnancy. For more information, please see the MotherToBaby fact sheet Paternal Exposures at https://mothertobaby.org/fact-sheets/paternal-exposures-pregnancy/.

An alkaloid from Hydrastis canadensis L., Berberidaceae. It is also found in many other plants. It is relatively toxic parenterally, but has been used orally for various parasitic and fungal infections and as antidiarrheal.
Berberine is a quaternary ammonia compound found in many botanical products, including goldenseal, barberry and Oregon grape, which is used for its purported antioxidant and antimicrobial properties for a host of conditions, including obesity, diabetes, hyperlipidemia, heart failure, H. pylori infection and colonic adenoma prevention. Berberine has not been linked to serum aminotransferase elevations during therapy nor to instances of clinically apparent liver injury.
Berberine has been reported in Stephania tetrandra, Coptis omeiensis, and other organisms with data available.
Berberine is a quaternary ammonium salt of an isoquinoline alkaloid and active component of various Chinese herbs, with potential antineoplastic, radiosensitizing, anti-inflammatory, anti-lipidemic and antidiabetic activities. Although the mechanisms of action through which berberine exerts its effects are not yet fully elucidated, upon administration this agent appears to suppress the activation of various proteins and/or modulate the expression of a variety of genes involved in tumorigenesis and inflammation, including, but not limited to transcription factor nuclear factor-kappa B (NF-kB), myeloid cell leukemia 1 (Mcl-1), B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xl), cyclooxygenase (COX)-2, tumor necrosis factor (TNF), interleukin (IL)-6, IL-12, inducible nitric oxide synthase (iNOS), intercellular adhesion molecule-1 (ICAM-1), E-selectin, monocyte chemoattractant protein-1 (MCP-1), C-X-C motif chemokine 2 (CXCL2), cyclin D1, activator protein (AP-1), hypoxia-inducible factor 1 (HIF-1), signal transducer and activator of transcription 3 (STAT3), peroxisome proliferator-activated receptor (PPAR), arylamine N-acetyltransferase (NAT), and DNA topoisomerase I and II. The modulation of gene expression may induce cell cycle arrest and apoptosis, and inhibit cancer cell proliferation. In addition, berberine modulates lipid and glucose metabolism.
An alkaloid from Hydrastis canadensis L., Berberidaceae. It is also found in many other plants. It is relatively toxic parenterally, but has been used orally for various parasitic and fungal infections and as antidiarrheal.
