How many hot ends do Indian club needles have?

Indian club needles are specialized acupuncture needles that are designed with specific features to enhance their functionality. These needles typically have one hot end, which is the end that is heated for the purpose of therapeutic treatment. The single heated end allows practitioners to provide heat into the acupuncture point or area being treated, which can enhance the overall effectiveness of the therapy by promoting blood circulation and alleviating pain.

In contrast, the other options suggest varying attributes that do not accurately describe Indian club needles. ‘Good seed’ is not a relevant term in this context, while the suggestions of having ‘two hot ends’ or ‘even activity’ do not reflect the standard design characteristic of these needles, which emphasize the single heated end for treatment purposes. Therefore, the correct understanding of Indian club needles hinges on recognizing that they feature one hot end used specifically for their therapeutic effects.
