Abigail's notes

Dandelion is the so-called weed that the entire world has been trying to poison out of existence and I genuinely grieve it. We have been conditioned to spray these things on sight, which is a great reason not to just grab one off the side of the road and eat it, because chances are someone has already doused it in chemicals. Which is so sad! Because the whole plant is usable and has been for a very long time.

The Chinese were using dandelion medicinally in the 10th century. The Arabs in the 11th. The Welsh in the 13th. Indigenous Americans eventually boiled the flower and drank the tea for heart disease. This is not a weed. This is an herb with a better historical resume than most things in your medicine cabinet.

The roots can be roasted and ground as a coffee substitute, which I respect as a concept even though nothing in this world substitutes coffee in my personal opinion. The young leaves can be eaten in salads and are only mildly bitter. Remember that scene in Ice Age where Sid makes a dandelion salad? That could be us. It really could.

Medicinally, dandelion helps optimize the body's nutrient uptake, supports healthy water balance as a diuretic, helps with fluid retention, supports poor liver function, and stimulates a poor appetite. For skin problems like acne, boils, and eczema it works particularly well when combined with echinacea.

Safety note: The milky juice of the plant should be kept away from small children as ingestion can cause vomiting or diarrhea. Otherwise dandelion is considered very safe and well tolerated. Just make sure whatever you're foraging hasn't been sprayed first.

Know your sources.
Magnifying glass over a web browser window, symbolizing source verification or fact checking.

Check the source, not just the headline

Who wrote it? What are their credentials? Who published it and why? A wellness blog and a peer-reviewed journal are not the same thing, even when they say the same words. Always click through to the original source.

Check the date

Science updates over time. A 2003 study on a supplement may have been contradicted twelve times since. Always look for the publication date and whether newer research exists. "Studies show" means nothing without a timestamp.

Follow the money

Who funded the study? A supplement company funding research on their own supplement is a conflict of interest. It's not automaticly a disqualification, but worth noting. Look for the "funding" or "disclosures" section of any study you read.

Understand study types

Not all research is equal. A randomized controlled trial carries more weight than a case study or an animal study. "A study found..." could mean ten people in a lab or a decade-long population study. The difference matters enormously.

Cross-reference everything

If only one source is saying something, be skeptical. If ten independent sources across different institutions, different countries, different decades are saying the same thing, you're getting warmer. Consensus is earned, not declared. Studies should be peer reviewed.

Use the NIH and examine.com

The National Institutes of Health database (PubMed) is free and searchable. Examine.com aggregates supplement research without selling anything. Both are significantly more reliable than any wellness influencer, including me.
