There is a point combination used for the Yangming stage with fever without sweating. I will analyze the point combination using the spherical flow.
The combination is Shangyang LI1‚ Hegu LI4‚ Yangxi LI5‚ Xiaxi GB43‚ Lidui ST45‚ Laogong P8 and Wangu SI4 (from the Great Compendium).
In the Yangming stage, the Yangming channel closes down, thus concentrating Qi in a heating cycle.
What points would you use to release the heat?
You would use points that unlock the Yangming channel:
St45 is used for heat conditions related to the stomach meridian. This point opens the St-Yangming channel to release heat.
What about Large intestine, the other half of the Yangming channel?
Above you see 3 points from LI that open up LI in order to release the heat in the heating cycle; LI1, LI4 and LI5.
Now on the spherical flow you have the following meridians connected in Sheng sequence. SI4 > LI points > Pc8 > GB43 > back to SI4. (cyclic connection of points.)
When an objective meridian is to be unlocked, it is common to see point combinations using a point from the preceding meridian, a point from a following meridian and a point from the objective meridian itself (according to the spherical flow).
Thus in this point combination, the goal is to unlock Large Intestine in a strong way, by using SI4 (preceding meridian) and Pc8 (following meridian). When LI is closed down strongly, sweating is stopped.
Such a strong use of points to unlock the LI should lead to sweating to cool down the body.
GB43 is added to balance LI and make feedback loop to SI4.
The points selected from the meridians correspond to releasing heat.
According to the spherical flow, the order of needling would be... St45 > Pc8 > SI4 > LI1 > LI4, LI5 > GB43. (Order of needling is following meridian, preceding meridian, then objective meridian.)
This point combination looks to be a very powerful one for releasing high fevers with no sweating during a Yangming syndrome.
