To answer your questions, we need to separate the "folk remedy" aspect of the soup from the scientific pharmacological concept of the therapeutic index.
1. Is tomato soup a "cure" for alcohol?
The short answer is no. There is no food or drink that "cures" or instantly neutralizes alcohol once it is in your bloodstream. Your liver processes alcohol at a constant rate (roughly one standard drink per hour), and nothing can speed that process up.
However, tomato soup provides a few things that can make you feel better:
- Hydration and Electrolytes: Alcohol is a diuretic (it makes you pee), leading to dehydration. Soup provides water and salt (sodium), which helps your body retain fluids.
- Potassium: Tomatoes are rich in potassium. Alcohol depletes potassium, and low levels can lead to muscle weakness or "the shakes."
- Blood Sugar: You mentioned the soup was a little sweet. Alcohol can cause blood sugar levels to drop (hypoglycemia), which contributes to dizziness and fatigue. The sugars in the soup provide a quick energy boost.
In essence: The soup doesn't remove the alcohol, but it treats some of the side effects of alcohol consumption.
2. What is a Therapeutic Index (TI)?
The Therapeutic Index is a quantitative measurement of the relative safety of a drug. It is a ratio that compares the amount of a drug that causes a therapeutic effect to the amount that causes toxicity.
The formula is generally expressed as: $$\text{TI} = \frac{\text{TD}{50}}{\text{ED}{50}}$$
- (Effective Dose): The dose that produces a desired effect in 50% of the population.
- (Toxic Dose): The dose that produces a toxic effect in 50% of the population.
High TI (Wide Window): If a drug has a very high TI, there is a huge gap between the "effective" dose and the "dangerous" dose. These drugs are generally safer (e.g., penicillin). Low TI (Narrow Window): If a drug has a low TI, the dose required to help you is very close to the dose that could harm you. These require precise dosing and constant monitoring (e.g., Lithium or Warfarin).
3. How does this explain what you are feeling?
While we don't usually talk about alcohol in terms of a "therapeutic index" (because it's a recreational toxin, not a prescribed medicine), the concept of the dose-response curve explains your situation perfectly.
The Dose-Response Relationship: You mentioned you usually have 1–2 shots to "feel the effect." This is your personal "effective dose" for a mild buzz. By moving to 4–6 shots, you have shifted your position on the dose-response curve.
- 1–2 Shots: You are in the "low dose" zone. Your liver can keep up with the clearance, and your brain is slightly inhibited, but your motor skills and judgment remain relatively intact.
- 4–6 Shots: You have moved closer to the "toxic" end of the spectrum. At this level, the concentration of ethanol in your blood is significantly higher. This leads to:
- Increased CNS Depression: Your central nervous system slows down more significantly.
- Liver Overload: Your liver is now working at maximum capacity to process the ethanol, leading to a buildup of acetaldehyde (a toxic byproduct), which causes that "fuzzy" or sick feeling.
- Dehydration: The higher dose of alcohol increases the diuretic effect, which is why the tomato soup (hydration/salt) felt helpful.
Summary: You didn't "cure" the alcohol with the soup; rather, you increased your dose beyond your usual tolerance, moving you further toward the "toxic" side of the index, and the soup helped mitigate the physical symptoms (low blood sugar and dehydration) associated with that higher dose.
Advice for now: Drink plenty of water, avoid taking any medication (like Tylenol/Acetaminophen, which can be hard on the liver when combined with alcohol), and rest.
