Actually no. There are two main differences:

1. Homeopathic remedies are made not only with plants, but also with animals and mineral and gases, and other tissues.
2. The main difference between herbal medicine and homeopathic remedies, even regarding the same plant, is that the homeopathic remedies are highly diluted while the herbal medicine is taken either as a tea or as a tincture, so they are not diluted at all.

For example, Aconite is a highly poisonous plant, herbalists cannot use it, but because it is highly diluted, it is very safe to be used in a homeopathic form. The remedy Aconite is extremely useful when something happens out of the blue, it is dramatic and intense. Yes, it is a good remedy in some cases of Panic attacks.
