Scutellaria Baicalensis/Baicalein Update

I am doing the groundwork for my Scutellaria baicalensis experiment, which has brought me to view a few new studies, such as one published in the November 2007 issue of “Molecular Cancer Therapeutics,” see abstract: (many thanks to a new friend for sending me the full study AND also to my friend Sherlock for trying to locate it).

Here’s a quick review taken from this study (you can also see my Page on Scutellaria baicalensis). Baicalein, extracted from the root of Scutellaria baicalensis, is an active flavonoid that has been found to have anticancer properties, leading “to cell cycle arrest and suppression of proliferation in cancer cells. And yes, in case you were wondering, that includes myeloma cells in vitro only, thus far. Hence, my upcoming experiment…on myself.

Baicalein (just like curcumin, let me add: see my link to the article on curcumin and survivin, right-hand side of my homepage) reduces the expression of survivin, a protein that inhibits apoptosis in cancer cells, including myeloma cells. If you need convincing that survivin (not to be confused with the adjective “SURVIVING,” by the way!) has relevance for myeloma, take a look at this February 2007 Leukemia abstract: My comment: survivin may be fascinating, but, according to the above-mentioned Molecular Cancer Therapeutics study, it is associated with decreased survival, unfavorable prognosis, and accelerated rates of recurrences in cancer therapy. Nothing “fascinating” about that, methinks…

Anyway, the Molecular Cancer Therapeutics study suggests that the inhibition of CDC2/cyclin B1 by baicalein contributes to the reduction of survivin and the proliferation inhibition in cancer cells. CDC2 is a kinase also present in myeloma…hmmm. Six flavonoids, baicalin, catechin, genistein, quercetin and rutin, in addition to baicalein, were examined by these researchers. The most toxic to bladder cancer cells was found to be baicalein, which was, and, this is significant!, NOT toxic to healthy cells. Does that sound familiar?

I have read the same thing over and over again: Toxic to cancer cells, Not Toxic to healthy cells! Okay, so where ARE the clinical trials!?! Well, quelle coincidence (!), since I wrote my May 31st post on Scutellaria baicalensis, two more clinical trials testing Scutellaria-derived substances have been added to the one I mentioned. One is testing an aqueous extract from herba Scutellaria Barbata D. Don on metastatic breast cancer patients; the other is testing a botanic formulation called PHY906, consisting of: Scutellariae baicalensis Georgi, white peony root, licorice, and the fruit of Fructus ziziphi (date). According to the patent application (see:, This specific formulation was established more than 1500 years ago for the treatment of diarrhea, abdominal spasms, fever, headache, vomiting, nausea, extreme thirst, and subcardial distention,” and “each herb possesses a distinct pharmacological profile that includes anticancer and antiviral activity, hematological and immunological stimulation, analgesic activity, vasodilation, liver protection, antioxidation, and appetite improvement. PHY906 is being tested together with a chemo drug on advanced pancreatic cancer patients. Well, three trials are better than just one, I suppose. If you want to read more about these trials, just go to

Speaking of clinical trials, according to the Molecular Cancer Therapeutics study, Although this study provides the potential cancer therapy of baicalein by human cancerous cells in vitro, the human cancer therapeutics by baicalein or combination of the survivin gene knockdown need to be determined by in vivo model before clinical trials. Moreover, the possible pharmacokinetic and toxicologic barriers need further characterization. Very true, but let me point out that Scutellaria baicalensis has been used as an anti-inflammatory remedy in traditional Chinese medicine for more than 2000 years to treat fevers, hypertension, coughing, and other ailments, according to Drugs dot com (see: This brings me to my warnings section.

Warnings: according to the Memorial Sloan-Kettering website, Scutellaria baicalensis MAY cause stupor, confusion, and seizures. Am I worried about that? Naaaah, not in the slightest. In the past, I have taken HUGE doses of antibiotics, even recently (now that I think about it), and if you paid any attention to the list of possible side effects associated with half the stuff you take for common ailments, you wouldn’t let it come within a few meters of you, let alone swallow it (or, worse, have your mother-in-law inject it into your hip, as happened to me earlier this fall when I was forced to take elephant-doses of antibiotics for a case of acute bronchitis…). The only other big warning about Scutellaria is that it may interact with cyclosporine, a drug that suppresses the immune system. And then there are the usual pregnancy or breastfeeding warnings, which don’t apply to my case anyway.

Final note: I would like to take this opportunity to thank the two people who have been sending me the full studies that give more “flesh” to my blog posts. One is my beloved Italian friend Sherlock, the other lives and works in the U.S. Thanks to them, I now have the FULL studies of the abstracts that I quoted in my first baicalein post. And much much more! Thank you so very very very much, both of you. Now, I just have to find the time to read all this stuff…eh!!!


  1. Hi Margaret,
    As you know I’ve been looking into celiacs disease and other allergic / digestive problems as a possible cause of MGUS/MM.
    Your heavy doses of antibiotics made me think you might like to take a look at the following URL:
    Surely it is important to make sure our digestive systems are in good order before taking curcumin etc – otherwise it won’t be absorbed properly – if at all.
    Best wishes,

  2. I am so pleased to know you have a world of wonderful people reading your blog, helping your quest and pulling together on a shared mission of hope and support. I can’t imagine how much time and effort it must take above and beyond earning a living to do your research.

    Know you are loved and appreciated, Margaret.

  3. Thank you SO much, LPC! Very kind of you! The feeling is mutual, believe me. When I began writing this blog, I had NO idea I would meet so many wonderful people. Right now, though, I am being “appreciated” by my kitten, Peekaboo, who wants me to get into the kitchen and feed her asap! 😉 I must dash off before she starts chewing on my monitor…hehe, Margaret

    Later in the day: thanks Paul, for the leaky gut link. I was excited at first, thinking I was going to the Leaky Cauldron (okay, that’s for the Harry Potter fans! 😉 )…instead, now I have to worry about this thing, too! ARGH! Seriously, though, more food for thought. Keep us posted on your research. Thanks! Margaret
