What is the first step for applying the four needle technique for a deficiency syndrome?

In applying the four needle technique for a deficiency syndrome, the initial step is to tonify the horary point on the mother channel. This approach is rooted in traditional Chinese medicine principles, where the mother element is associated with nurturing and supporting actions within the meridian system. The horary point indicates a time of peak energy for that channel, making it an ideal location for enhancing its function.

By starting with the mother channel's horary point, practitioners aim to strengthen the overall energy of that channel, particularly beneficial for conditions characterized by deficiency. This strategy aligns with the fundamental idea that strengthening the mother element can, in turn, improve the health and vitality of the child element, effectively addressing the deficiency.

The other options suggest different actions that are more appropriate for other scenarios or specific balancing techniques rather than beginning the process for deficiency syndrome. The four needle technique emphasizes the importance of building the foundational energy first before proceeding with any further adjustments or sedative techniques.
