Recently I wrote a post about research investigating an interesting compound called Epigallocatechin gallate (or EGCG – click here for that post). Several eagle-eyed readers, however, noted something interesting in the details of one of the research reports that was discussed in that post.
The study in question had used EGCG as a positive control for evaluating the ability of other compounds for their ability to inhibit the clustering of Parkinson’s-associated protein alpha synuclein.
But there was also a second positive control used in that study.
It is called baicalein.
In today’s post, we will discuss what baicalein is and what research has been done on it in the context of Parkinson’s.

Once upon a thyme, in a far away land, there was a mysterious little flowering plant.
The “far away land” was the southern parts of eastern Siberia.
And the flowering plant is Scutellaria baicalensis – which is more commonly referred to as Baikal skullcap.
What is Baikal skullcap?
Baikal skullcap is a perennial herb that is indigenous to Southern Siberia, China and Korea. For centuries, traditional Chinese medicine has used the dried roots – which is called huángqín (Chinese: 黄芩 or golden root) – for a variety of ailments.

The plant grows to between 1-4 feet in height, with lance head-shaped leaves and blue-purple flowers. Baikal skullcap belongs to the same family of flowering plants (Lamiaceae) as thyme, basil, mint and rosemary.
For traditional Chinese medicinal use, the roots are usually collected in spring or autumn once the plant is more than 3-4 years old. They are dried and then used to treat hypertension, to reduce “fire and dampness”, and to treat prostate & breast cancers.
And one of the key constituents of Baikal skullcap (and huángqín) is a compound called baicalein.

BE WARNED: THIS POST MIGHT UPSET SOME READERS
A recently published research report has caused a bit of a fuss in the media, and I have been contacted by a lot of concerned readers regarding this particular study.
It deals with some chemicals – which can be found in everyday products – that may be having a negative effect on biological processes that are related to Parkinson’s disease – specifically, the normal functioning of the mitochondria (the power stations of each cell).
In today’s post we will discuss the new research, what the chemicals do, and whether the Parkinson’s community should be concerned.
It is something that most of us take completely for granted in the modern world. A product that sits in our bathroom, by the sink or on a shelf, and 2-3 times per day we stick some of it in our mouth and brush it around a bit. Given the well ingrained habit of repetitively ingesting of the stuff, we have little trouble with the idea of switching brands or trying new variations (“Oooh look, this one will make your teeth whiter. Let’s try it”).
I mean, come on – it’s just toothpaste. It’s safe, right?
It probably won’t surprise many of you to learn that the composition of toothpaste has changed quite a bit over the years, but what might amaze you is just how many years are involved with that statement:

The Egyptians recognised the importance of looking after one’s teeth at a very early stage. Apparently they had a lot of trouble with their teeth because their bread had grit in it which wore away their enamel. As far back as 5000BC, they had a form of toothpaste that they used to clean their teeth. It was a mix of powdered ashes of ox hooves, myrrh, powdered and burnt eggshells, and pumice (Source: Wikipedia). The Greeks, followed by the Romans, improved on the recipes (by adding abrasive ingredients such as crushed bones and oyster shells – delightful, huh?), but it wasn’t until after World War I that the modern day pre-mixed toothpastes became popular.
The cavity fighting chemical, Fluoride, was first added to toothpastes in the 1890s, and in 1908 Newell Sill Jenkins (an American dentist) invented the first toothpaste that contained disinfectants. It was called Kolynos (from the Greek words Kolyo nosos (κωλύω νόσος), meaning “disease prevention”).
Following the advent of Kolynos, most toothpaste companies added antiseptic and disinfectant agents to improve the quality and effectiveness of their product. Being offered a tooth cleaning product with magical antibiotic properties seemed to reassure consumers that they were buying something that might actually work. And this led to more and more chemicals being added to toothpaste. Such additions included chemical like triclosan, cetylpyridinium chloride and benzalkonium chloride.
These chemicals are safe though…right?
