It grows 60-100 cm tall, with a branching stem and opposite, ovate-shaped leaves that are 2-5 cm long and 1-3 cm wide. The plant produces small, tubular flowers in shades of blue, purple, and white, which are clustered in axillary whorls and have a calyx that is campanulate and 6-7 mm long. The flowers bloom in July and August, producing a four-cuspidate corolla and a calyx with four teeth.

The plant's root is used in traditional medicine, primarily in the treatment of fever, cough, and gastrointestinal disorders.

What ailments can you heal with this herb?

The most common ailments you can heal with Scutellaria baicalensis are inflammation, fever, and diarrhea, which are effectively reduced by its flavonoids, specifically baicalein and baicalin.

Baicalin has also been shown to inhibit the growth of hepatitis B virus in liver cells. Additionally, its flavonoids exhibit bronchodilatory effects, making it an effective treatment for cough, while its flavonoids and phenolic acids have been found to lower blood pressure, thus treating hypertension and cardiovascular disease. Scutellaria baicalensis has also been used to treat gastritis, gastroenteritis, and dyspepsia due to its gastroprotective and anti-inflammatory properties.

Furthermore, its flavonoids have been demonstrated to have antidiabetic effects, and have been shown to inhibit the growth of cancer cells, including those of leukemia, while also reducing the risk of high blood pressure, nausea, skin conditions, malaria, anxiety, asthma, migraines, and rheumatism.

What are the therapeutic properties this herb?

The main therapeutic properties of Scutellaria baicalensis are attributed to its antioxidant activity, which helps in neutralizing free radicals and protecting the body from oxidative stress.

The anti-inflammatory property of this plant is primarily due to the presence of flavonoids, such as baicalein and baicalin, which have been shown to inhibit the production of pro-inflammatory enzymes and cytokines, thereby reducing inflammation and alleviating conditions like arthritis. Scutellaria baicalensis also exhibits antimicrobial properties, which are largely attributed to its saponin content, enabling it to inhibit the growth of various bacteria and fungi, including those responsible for respiratory infections like bronchitis and pneumonia. Additionally, the neuroprotective effects of this plant are associated with its ability to cross the blood-brain barrier and protect neuronal cells from damage, thereby alleviating conditions like Alzheimer's disease and Parkinson's disease.

Its antiviral properties, largely attributed to its flavonoid content, enable Scutellaria baicalensis to inhibit the replication of viruses like herpes simplex and HIV, making it a potential candidate for the development of antiviral medications.

What are the medicinal constituents this herb?

The most important healing constituents of Scutellaria baicalensis are wogonin, baicalein, baicalin, oroxylin A, and baicalein-7-O-glucuronide, which are responsible for its medicinal properties due to their potent antioxidant, anti-inflammatory, and neuroprotective effects.

Baicalein, a flavone glycoside, exhibits anti-inflammatory activity by inhibiting the production of pro-inflammatory cytokines, such as TNF-α and IL-1β. Baicalin, a flavone glycoside, has been shown to possess antioxidant and anti-inflammatory properties by scavenging free radicals and inhibiting the production of pro-inflammatory enzymes. Wogonin, a flavone, has been found to exhibit neuroprotective effects by inhibiting the production of pro-inflammatory cytokines and modulating the NF-κB signaling pathway.

Oroxylin A, a flavone, has been reported to possess antioxidant and anti-inflammatory properties by scavenging free radicals and inhibiting the production of pro-inflammatory enzymes.

What are the main herbal preparations this herb?

The main herbal preparations of Scutellaria baicalensis are baicalin capsules, a concentrated form of the flavonoid baicalin, which has been shown to have anti-inflammatory and antioxidant properties.

Baicalein extract is another preparation that has been found to possess immunomodulatory effects, making it useful for reducing inflammation and improving immune function. Scutellaria tincture, a liquid extract of the plant, has been traditionally used to treat fever, headaches, and other conditions related to inflammation. Baicalin extract is a highly concentrated form of the flavonoid baicalin, which has been shown to have hepatoprotective effects, making it useful for treating liver damage.

Baikal skullcap tea, a traditional preparation made by infusing the dried roots of the plant in hot water, has been found to have anti-inflammatory and antioxidant properties, making it useful for reducing inflammation and improving overall health.

What are the possible side effects of using this herb improperly?

The possible side effect of using Scutellaria baicalensis are increased bleeding risk due to its ability to inhibit platelet aggregation and function, which may interact with warfarin and other blood thinners such as heparin and aspirin, leading to additive effects and exacerbating bleeding complications.

This herb may also interact with anticoagulants like dabigatran and rivaroxaban, further increasing the risk of bleeding. Additionally, Scutellaria baicalensis may cause nausea due to its emetic properties, which can lead to discomfort and potential dehydration in some individuals. The mechanism behind these interactions is attributed to the herb's flavonoids and phenolic acids, which can alter the activity of certain enzymes and receptors involved in blood clotting and coagulation.

Therefore, individuals taking Scutellaria baicalensis should consult with their healthcare provider to monitor potential interactions and bleeding risks.
