Mills presents a traditional decision rule: first ask whether the person naturally seeks heat or cold for the symptom, then test a low-dose preparation in the corresponding direction. In his examples, ginger, cinnamon, fennel, and spices are warming, while peppermint and bitter preparations are described as cooling. He recommends beginning with teas because their lower dose makes them useful for observing individual response. The result is not a diagnosis or proof of efficacy; it is a cautious preference test that may narrow what feels tolerable or useful. Mills also stresses individual variation, noting that ginger can upset some stomachs or feel overly stimulating. Persistent, severe, or unfamiliar symptoms still require appropriate clinical care.

Core principles
- 01Begin with how the symptom responds to heat or cold
- 02Start with a low-dose form
- 03Use direct response as information
- 04Stop when the response is unpleasant or unclear
How to run it
- 1
Classify the preference
Ask whether the symptom feels better with warmth or cooling. Use the person's actual experience rather than the condition's label.
Pro tip A preferred hot-water bottle or ice pack can reveal the direction.
Watch out Temperature preference is not a medical diagnosis.
- 2
Select a low-dose trial
Choose one simple tea in the preferred direction, such as ginger for warming or peppermint for cooling, after checking safety.
Pro tip Use one ingredient or a simple combination so the response is easier to interpret.
Watch out Pregnancy, medications, allergies, and existing conditions can change what is safe.
- 3
Observe the response
Notice comfort, symptom change, stomach response, and unwanted stimulation during and after the trial.
Pro tip Record what happened and how quickly.
Watch out Stop if the preparation worsens symptoms or causes an adverse effect.
- 4
Keep, switch, or escalate
Retain the option only if it is well tolerated and useful. If the response is poor, abandon the trial; if the symptom persists or is serious, seek clinical advice.
Watch out Do not delay antibiotics or other necessary treatment for a serious infection.
In the wild
During the interview, Mills prepares grated ginger and cinnamon in hot water. The host reports feeling warmth straight away and says the drink tastes pleasant. Mills uses this immediate response to illustrate the test, while later noting that some people cannot tolerate ginger because of stomach upset or overstimulation.
→ The host reported an immediate warming sensation; no therapeutic outcome was established.
Common mistakes
Matching the label, not the response
Mills says people with the same label can prefer opposite temperature directions. Ask what actually feels better.
Starting too strongly
A concentrated product makes tolerability harder to judge and can increase risk. Begin with a low-dose preparation if a trial is appropriate.
Is it for you?
Best for
It is best for cautious exploration of familiar, mild symptoms after contraindications have been checked.
Not ideal for
It is not suitable for serious infection, unexplained pain, high-risk patients, or symptoms needing diagnosis.
From the transcript
“I will suggest that they start with herbal teas because herbal teas are a very low dose.”
“Would you prefer ginger or peppermint tea? And already you're beginning to narrow things down a bit.”
