No. Germanium is a natural element and even marketed as a dietary supplement. It is possible to overdose on the supplement but only if one were to take too many supplements. It is highly unlikely that someone would encounter that high of Germanium levels naturally.
That being said, the manufacture of Germanium Substrate for use in electronics (and photovoltaic solar panels) results in hazardous by-products. As a result, there is no cost-effective and safe (according to the EPA) way to produce Germanium Substrate in the U.S., without violating EPA regulations. Most of the Germanium Substrate production for use in the U.S.A. is done in Canada or other countries.
Germanium does no "do" anything.
neither, germanium is a semiconductor

The Carbon Family
GeH4 is called germane, germanium hydride, geranium tetrahydride, or monogermane.
Germanium compounds are toxic.

Germanium is not manufactured; its ore is mined then refined into germanium.
Four reasons. First, it is a LOT cheaper and easier to get silicon. Germanium is a trace element in rocks. You need to mine and process lots of rock to get any germanium. Silicon is also known as sand--very easy to find. Second, germanium is heat sensitive. It's harder to solder a germanium device in than a silicon one because the heat can mess up the germanium. Germanium devices pretty much have to be soldered in by hand because you have to heat sink them, whereas silicon devices can be soldered in a soldering machine. Third, germanium's hazardous and silicon is generally not. People eat off glass plates, which are made from silicon. They do NOT eat from germanium plates, if they could even afford them. And fourth, germanium has a variable voltage drop--the higher the voltage, the greater the drop. If you pump 5000 volts into a silicon diode, you're going to get 4999.3v out the other side.
