Our website is optimized for the Firefox and Google Chrome web browsers. You can use any browser, but if you experience issues, please try a different browser.

While the wesbite seems fairly simple, clean and easy to navigate, there’s a lot going on under the hood. To ensure you have a seemless, easy user experience, please make sure Javascript is enabled.


To read some of the downloadable articles on the website, you’ll need a copy of Adobe Acrobat Reader or other PDF viewer.


We use standard video streaming technology to deliver video content. Most web browsers should have no problem handling our videos (public and members), but our website is optimized in the Firefox or Google Chrome web browsers. You can use any browser, but if you experience issues, please try a different browser.


To stream the videos on our website, your internet speed should be at least 3-5 mbps. If your internet speed is less than 3 mbps, we can’t guarantee that you’ll be able to stream without interruption. Not sure what your internet speed is? Call your internet service provider (Comcast, Time Warner, Telecom, Vodafone, etc.).

You can also run a speed test. Follow the link below and make sure to “Start Test”.

Note: Internet service providers often throttle bandwidth. Your service plan’s speed isn’t always the amount of bandwidth being delivered. Being on a network with other users in your home, neighborhood, office, school, or cafe will often slow your speed since the bandwidth is being shared by you and other users. We recommend using a network with less users.

›› I’m having difficulty watching the videos on the site or viewing some of the content. What should I do?

Be sure you have the Mozilla Firefox or Google Chrome browser installed. Most browsers should work right out of the box, but if you find there are some issues in how the website appears to function, please be sure to enable Javascript in the browser itself. Javascript is a commonly used language on the web.

›› Is the membership $195?

Yes it is! Several times a year we also offer a discounted rate (usually $175). We have not increased the price of an Individual Membership for over 10 years.

There are 160+ hours of video and audio presentations and more than thirty articles not featured in the public pages of the website. We upload at least 1 video per month for members, usually an hour-long presentation by Prof. Fruehauf and his colleagues. The educational information contained in the presentation and articles may be clinically and/or scholarly relevant material that will benefit most practitioners and students of Chinese medicine.

You can view our current inventory, watch sample videos, and read excerpts from a variety of articles by visiting the membership information page below.

›› Does Prof. Fruehauf ever offer online, live webinars or teleconferences?

Dr. Fruehauf currently has courses available on various partner websites. All courses are eligible for PDA/CEU credit. There is a vast library of classes to choose from on both major partner websites.

Membership to this website does not include PDA credit.

›› Will you ever sell individual articles and videos currently only available to members so I don’t need to commit to a full year? I’m looking for specific content.

Currently, several articles in the membership pages are for individual sale. You will find those in our Store. We are also working to introduce several of the video series in a pay-per-view model, which will allow viewers to custom build their learning program. Still, a full membership is the most cost effective way to go.

›› Is your website GDPR-compliant?

GDPR, or General Data Protection Regulation (2016/679), is a regulation in EU law on data protection and privacy for all individuals within the European Union and the European Economic Area. It also addresses the export of personal data outside the EU and EEA. We have done an extensive audit of user personal and computer information on our website, including how it’s used. Our primary goals are consent and transparency. To that end, we welcome you to read our Privacy Policy if you have questions or concerns. As a user to our website, you can also request to have your data deleted.

›› What’s the difference between classical Chinese medicine and traditional Chinese Medicine?

This is a long and complicated conversation that scholars have been arguing about for a long time. We don’t intend to answer that question ourselves on this site but rather present material that supports your learning about classical Chinese medicine. It is our hope that this site will be used as a tool for both learning and discussion. For now, please view the content in the public section of the website, or search for your topic in the search box. We welcome constructive comments and dialogue amongst our readers following each of the posted articles.

One article that may be a good place to begin: Chinese Medicine in Crisis: Science, Politics, and the Making of “TCM”

›› Can you tell me more about how your website is organized?

The website is organized topically based on the clinical work and scholarship of Heiner Fruehauf and his colleagues and friends. The topics are divided into articles and videos (with some podcasts). Each type of media contains content available both to the public and members. Of particular interest to us are Chinese herbal medicine, Chinese cosmology and symbol science, classical medical text translations, and qigong, Daoist medicine, and self cultivation practices.

The navigation menus will get you started. Then choose a topic from the dropdown menus. On each topic page, the available content is displayed as individual posts, like an index.

If you’re looking for a specific topic and are unsure where to find it, you can always use the search tool in the navigation bar.

›› What’s the difference between the dark gray menu above the white menu in the header?

The upper navigation menu bar above the header image contains menu links that tell you about us, educational opportunities, our organization, site administrative details, and support information (where you found this page).

The main navigation menu next to the logo is where the site content is located – videos, articles, membership information, and the store.
