"Please give examples of pseudoscience, but leave aside pseudoscience".
But fine, let's skip eugenics.
* Ahnenerbe - racial heritage of German people, and plenty of occultism
* Large parts of their human experimentation.
* "Social Darwinism". (Granted, runs into eugenics. But it's the foundational belief under the whole regime, so hard to avoid)
* Phrenology
* "Jewish physics" - discarding Einstein completely. Trying to get Heisenberg & Quantum Physics, as well, but turned out his science worked a little too well to discard.
* The idea that women can't get pregnant from rape[1]
In general, you'll find much of the "bad" science in the softer sciences - the more soft, the worse. The reason is that it's easier to maintain a fraud if the field doesn't expect clear reproducible answers.
The harder sciences were affected via Aryanization - e.g. Chemistry lost 25% of all its academics in the runup to 39.[2]
