What is known and what has been learned about Scutellaria bicalensis and Eleutherococcus senticosus radix? The following are excerpts from selected publications describing the research performed with Scutaellaria baicalensis and Eleuthrococcus senticosus. This is a small sample of the extensive work that has been accomplished by many researchers who were interested in these compounds. It is not our intention to introduce our own commentary with respect to their work, nor is it our intention to create a connection to our product. It is our intention to show that these herbals have undergone a great deal of scrutiny and that they have been proven to be safe for general use.

Phytochemicals of different chemical classes result in often complex mixtures typically containing many natural products and their derivatives. In phytotherapy it is believed that mixtures of active compounds act and have a concerted, multileveled molecular action [1]. Thus,the different compounds present in herbal extracts potentially act in a synergistic and/or antagonistic manner on specific or multiple targets[1]. [1] Williamson EM. Synergy and other interactions in phytomedicines. Phytomedicine2001;8(5):401-9.


Scutellaria baicalensis (Baikul skullcap) and eleutherococcus senticosus (Siberian ginseng), have been used by natural medicine practitioners all over the world for hundreds of years. Phytochemicals of different chemical classes result in often-complex mixtures that typically contain many natural products and their derivatives. In phytotherapy, it is believed that mixtures of active compounds have a concerted, multilevel molecular action [1]. Thus, the different compounds present in herbal extracts potentially act in a synergistic and/or antagonistic manner on specific or multiple targets [1].
These two ingredients have been studied and used for many years, with an excellent safety profile, and little to no adverse effects (see section on Dosage and Administration below). When adverse effects were reported, these were primarily related to their use as an adjuvant to chemotherapy.

    1. Scutellaria baicalensis
      • Baikal skullcap (Scutellaria baicalensis) is a perennial herb native to southern Scutellaria species.
      • Traditional uses include anti-inflammatory, antibacterial, antifungal, antiviral, neuroprotective, and anticancer applications.
      • According to secondary sources, Scutellaria baicalensis root is widely used in China as an adjuvant to chemotherapy for lung cancer and other cancer related studies. However, although scutellaria baicalensis has been used as an adjunct to chemotherapeutic agents, at this time, there is no evidence to support any beneficial effects in that application.
      • Numerous studies have, however, reported the antioxidant effects of Scutellaria baicalensis, which may contribute to its neuroprotective effects and beneficial effects on the immune system. It has also been found to modulate various inflammatory pathways. According to a review, flavones from the root of Scutellaria baicalensis Georgi may have neuroprotective properties, as shown in both oxidative stress-induced and amyloid-beta- and alpha-synuclein-induced neuronal death models [2]. In mice, an aqueous extract of Scutellaria baicalensis Georgi improved the immune response to the administration of UV-attenuated Toxoplasma gondii, as evidenced by prolonged survival time, decreased parasite burden, improved liver histopathological score, and increased Th1-type cellular immune response [3].
      • Several reports have also described the efficacy of Scutellaria baicalensis for allergies [4], as an antibacterial [5, 6-10], as an antifungal [8,11], as an anti-inflammatory [4, 5, 12-14], as an antiseptic [8], and for bronchitis [11], candida infection [15], and methicillin-resistant Staphylococcus aureus (MRSA) [16]. However, for these applications, the available reports lack sufficient evidence of efficacy.



      • Antiallergy effects: Baicalin from Baikal skullcap inhibited histamine and leukotriene release from mast cells in vitro [17].
      • Antibacterial effects: Radix Scutellariae inhibited Porphyromanus endodontics in vitro by making them become bigger, longer, and crumbled [7]
      • Antifungal properties: A laboratory study indicated that Baikal skullcap may have anti-Candida properties [11,15]. Baicalin also had anti-Candida effects in vitro [9]. Baicalein inhibited pathogenic yeasts with MICs of 70-100mcg/mL; no inhibitory effect was observed upon dermatophytes and filamentous imperfect fungi [8].
      • In vitro, the water extract of the root of Scutellaria baicalensis, as well as constituents such as wogonin, inhibited aflatoxin B1 oxidizing cytochrome P450 enzymes (mainly CYP1A1/2) [18].
      • Anti-inflammatory effects: According to a review and laboratory studies, Baikal skullcap and its constituents may have immunomodulatory effects, based on the modulating effects of cytokines (interleukins and interferons), eicosanoids, nitric oxide, monocyte chemotactic protein 1, macrophage inflammatory protein (MIP)-1alpha, and MIP-1beta mRNA and protein [4, 19, 20-22]).
      • In a zymosan-induced mouse air-pouch model, an herbal preparation using Scutellaria baicalensis reduced the expression of nitric oxide (NO), inducible NOS (iNOS), cyclooxygenase (COX)-2, prostaglandin E2 (PGE2), nuclear factor-kappaB (NF-kappaB), and IkappaB-alpha, as well as inflammatory cytokines, such as IL-1beta, IL-2, IL-6, IL-12, and TNF-alpha, and exerted similar effects by decreasing the expression of iNOS and COX-2, IkappaB kinase-alpha/beta (IKK-alpha/beta) phosphorylation, and IkappaB-alpha and IkappaB-alpha phosphorylation in LPS-treated RAW264.7 cells [20, 21]. In a rat model of pelvic inflammation, Scutellaria baicalensis decreased TNF-alpha and IL-6 levels, although to a lesser extent than was observed for Curcuma wenyujin [19].
      • In vitro, baicalin inhibited superantigen-induced inflammatory cytokines and chemokines [23]. The stimulated T cell proliferation, as well as production of interleukin-1beta, interleukin-6, tumor necrosis factor, interferon-gamma, monocyte chemotactic protein-1, macrophage inflammatory protein (MIP)-1alpha, and MIP-1beta mRNA and protein by human peripheral blood mononuclear cells, was reduced. Both baicalein and baicalin inhibited LPS-induced inducible nitric oxide synthase (iNOS) protein expression, iNOS mRNA expression, and NO production in a dose-dependent manner. In vitro, the anti-inflammatory effects of Scutellaria baicalensis were found to be potentially related to IL6ST down-expression and overexpression of CD98 [24]. In human endothelial cells in vitro, wogonin inhibited monocyte chemotactic protein-1 gene expression and secretion [25]. The inhibition was found to be mediated by reducing AP-1 transcriptional activity via the attenuation of ERK1/2 and JNK signal transduction pathways. In vitro, baicalin-induced anti-inflammatory activity was found to be due to chemokine binding [26]. Baicalin was found to cross-link with oxime resin bound chemokines of the CXC (stromal cell-derived factor (SDF)-1alpha, IL-8), CC (macrophage inflammatory protein (MIP)-1beta, monocyte chemotactic protein (MCP)-2), and C (lymphotactin (Ltn)) subfamilies. In vitro, baicalein affected lipopolysaccharide (LPS)-induced cyclooxygenase-2 expression through inhibition of C/EBPbeta DNA-binding activity [27]. In vitro, baicalein inhibited interleukin-1beta- and tumor necrosis factor-alpha-induced endothelial leukocyte adhesion molecule-1 (ELAM-1) and intercellular adhesion molecule-1 (ICAM-1) expressions in cultured human umbilical vein endothelial cells [28].
      • Ex vivo, baicalin inhibited IL-8 induced degranulation of human polymorphonuclear leukocytes [12]. In vitro, wogonin suppressed the mite antigen-induced thymus- and activation-regulated chemokine (TARC) expression via the induction of heme oxygenase 1 (HO-1); this suppression was restored by HO1 siRNA [29].
      • In animal research, baicalin attenuated inflammation in cigarette smoke-induced inflammatory models by inhibiting NF-kappaB activation [30].
      • Antiretroviral effects: In vitro, Scutellaria baicalensis inhibited (at 200mcg/mL) human immunodeficiency virus type-1 protease (HIV-1 PR) (54). In vitro, the enzymatic activity of purified recombinant HIV-1/RT was inhibited by baicalin, as was the activity in infected cells [31].
      • In vitro, baicalin was found to interfere with the interaction of HIV-1 Env with chemokine coreceptors and block the entry of HIV-1 into cells [32]. According to computational investigation of the anti-HIV activity of baicalein, baicalein bound to the active site region of the HIV-1 integrase [33].
      • Various reviews have been published that discuss the anti-HIV effects of Scutellaria baicalensis and its constituents [34].
      • Antisepsis effects: 2′,5,6′,7-Tetrahydroxyflavanonol (THF) from Scutellaria baicalensis Georgi downregulated TNF-alpha mRNA expression but also decreased TNF-alpha and IL-6 release from RAW264.7 cells induced by lipopolysaccharide (LPS), a known trigger in the pathogenesis of sepsis [35]. In vivo, THF significantly protected mice against a lethal challenge with heat-killed E. coli 35218.
      • Antiviral effects: Baicalein and wogonin, Scutellaria baicalensis flavones, modulated cytokine production, as evidenced by inhibition of IFN-alpha and IFN-gamma and stimulation of TNF-alpha and IL (IL-10, IL-12) production in human leukocytes exposed to vesicular stomatitis virus [36]. In vitro, wogonin suppressed hepatitis B surface antigen production; both circular and the linear forms of HBV DNA were significantly reduced [37]. Radix Scutellariae suppressed HBV gene expression and virus production in human hepatoma cells in vitro [38].
      • Immune effects: Baicalein- and wogonin-containing extracts inhibited IFN-alpha and IFN-gamma and stimulated TNF-alpha and IL (IL-10, IL-12) production; the resistance of peripheral blood leukocytes to vesicular stomatitis virus was augmented [36].
      • In vitro, baicalin inhibited superantigen-induced inflammatory cytokines and chemokines [23]. The stimulated T cell proliferation, as well as production of interleukin-1beta, interleukin-6, tumor necrosis factor, interferon-gamma, monocyte chemotactic protein-1, macrophage inflammatory protein (MIP)-1alpha, and MIP-1beta mRNA and protein by human peripheral blood mononuclear cells was reduced. In vitro, the immune effects of Scutellaria baicalensis were found to be potentially related to ISGF3G overexpression [24].

  1. Eleutherococcus senticosus
    • Siberian ginseng (Eleutherococcus senticosus, Acanthopanax senticosus) is a small, woody shrub in the Araliaceae family native to southeastern Russia, northern China, Korea, and Japan [1]. Although it is not related to true ginseng (Panax ginseng), the name Siberian ginseng became popular based on properties that were similar to Panax ginseng. Siberian ginseng is also called “eleuthero” in some products.
    • Traditionally, Siberian ginseng has been used as an adaptogen and for increased endurance and memory improvement, as well as for chemoprotection, immunological enhancement, and overall well-being. Overall, there is currently little clinical evidence on the use of Siberian ginseng for these indications.


General: Several reviews discuss the antioxidant, antistress, antiulcer, anti-irradiation, anticancer, antifatigue, anti-inflammatory, immunostimulant, cardioprotective, wound-healing, and hepatoprotective activities of Siberian ginseng [1-3]


The effect of Siberian ginseng on immunological endpoints has been investigated in various groups, including athletes, healthy individuals, and cancer patients. In two clinical trials [4,5] and one combination study (containing Leuzea carthamoides, Rhodiola rosea, Eleutherococcus senticosus, and fruits of Schizandra chinensis) [6], Siberian ginseng showed stimulatory effects on T helper cells, immunoglobulin levels, and natural killer cells. No effect was found in a third study [7]. The methodological quality of most studies was low. Further research using well-designed clinical trials is required before conclusions can be made.

Evidence: Gaffney et al. conducted a randomized controlled trial to compare the effects of Siberian ginseng with Panax ginseng and placebo on immune response in competitive endurance athletes engaged in their normal training [7]. Ten matched groups of participants were included (N=30). Participants were included if they had at least two years of endurance training experience, had trained on average at least five hours weekly for the previous three months, were between the ages of 18 and 40 years, did not use medications likely to affect the dependent variables, were training in preparation for competition within the season that the study was undertaken, and were in a group of three training partners matched for training volume and intensity. According to the authors, training partners were considered to be matched if they trained one or more times per week with the other two participants in their group. Subjects received a 35% ethanolic extract of Siberian ginseng (8mL daily, equivalent to 4g of dried root), or a 60% ethanolic extract of Panax ginseng (4mL daily, equivalent to 2g of dried root diluted to the same volume as Siberian ginseng), or placebo. Endpoints included stress hormones (cortisol and testosterone) and immunological markers (B lymphocytes, T cells, and CD4, CD8, and natural killer cells). Treatment had no effect on Bohn et al. conducted a placebo controlled study to examine the effect of a Siberian ginseng extract (Eleu-kokk ®) on immune system function in 36 healthy volunteers [4]. Volunteers received 10mL of an ethanolic extract (vincamine-free) of Siberian ginseng or placebo (wine) three times daily for four weeks. The main endpoint was cellular immune status, as determined by quantitative flow cytometry. Siberian ginseng use resulted in an increase in the absolute number of immunocompetent cells, mainly T helper cells. There were also effects on cytotoxic and natural killer cells. There were no side effects observed over a six-month period. Additional details are currently lacking.

Background. Patients seek an effective alternative to pharmacotherapy including herbal treatment options for allergic rhinitis and rhinosinusitis.

 Material and Methods. Nasal mucosal tissue was obtained from 12 patients, fragmented, preincubated with tissue culture medium, S. baicalensis and/or E. senticosus and/or vitamin C (each compound 0.2 gμ/mL and 2 μg/mL) for 1 hour at 37°C/5% CO2, and stimulated with anti-IgE for 30 minutes and 6 hours to imitate the allergic early and late phases. Furthermore, Staphylococcus aureus superantigen B (SEB) stimulation for 6 hours was used to imitate T-cell activation.

Results. The combination of S. baicalensis and E. senticosus had a more potent suppressive effect on the release of PGD2, histamine, and IL-5 than S. baicalensis alone. The combination also resulted in a significant inhibition of SEB-induced cytokines comparable or superior to an established topical corticosteroid, fluticasone propionate. Vitamin C increased ciliary beat frequency, but had no anti-inflammatory effects.

 Discussion. The combination of S. baicalensis and E. senticosus may be able to significantly block allergic early-and late-phase mediators and substantially suppress the release of proinflammatory, and Th1-, Th2-, and Th17—derived cytokines.
