Geranium can generally treat diseases such as arthritis, rheumatism, bruises and sprains, skin itching, dysentery, and more. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed analysis is as follows:

1. Arthritis: Geranium has the effect of dispelling wind and removing dampness, which can relieve joint pain and swelling caused by wind-cold-damp pathogens. It is especially suitable for patients with chronic arthritis as an adjunctive treatment.

2. Rheumatism: The active ingredients in geranium can promote blood circulation, dispel dampness in the body, and alleviate muscle aches and joint stiffness caused by rheumatism. It is one of the commonly used herbs in traditional Chinese medicine for treating rheumatism.

3. Bruises and sprains: Geranium has the effect of promoting blood circulation and resolving blood stasis, which can accelerate the repair of damaged tissues and relieve bruising and swelling caused by injuries. It is often used externally or internally in combination with other Chinese herbs.

4. Skin itching: Geranium contains antibacterial and anti-inflammatory components that can inhibit bacterial growth on the skin surface and relieve itching caused by eczema, urticaria, or other skin conditions. It is suitable for external washing or making into a decoction for bathing.

5. Dysentery: Geranium has the effects of clearing heat, detoxifying, and astringing to stop diarrhea, which can improve symptoms of dysentery caused by damp-heat, such as abdominal pain, diarrhea, and bloody stools.

Some individuals may be allergic to components in geranium, presenting symptoms such as rashes, itching, or difficulty breathing. People with allergic constitutions should avoid using it.
