Seven top takeaways from the Integrative Practitioner Summit on environmental medicine

5. Herbs can help facilitate detoxification through the liver, gallbladder, kidneys, and skin.

According to Ingels, plants such as peppermint (Mentha piperita), cayenne (Capsicum frutescens), and dandelion (Taraxacum officinalis), are known as “mild liver botanicals.” When used correctly, these plants can help promote better digestion and better peristalsis while having a mild impact on the liver itself.

In addition, there are stronger liver botanicals. These, Ingels explained have a more stimulating effect on the liver itself. Plants considered strong liver botanicals include plants such as blue flag iris, greater celadine (cheidonium majus), and milk thistle (Silybum marianum). These plants can help stimulate secretion of pancreatic enzymes, improve circulation in the liver, and protect the liver against oxidative damage.

As for using botanicals as laxatives for detoxification, getting the right dose is essential. Plants like cascara (Rhamnus purshiana), senna (Cassia angustifolia), and black walnut (Juglans nigra), are all going to cause diarrhea, Ingels said.

“But again, it's about dose,” he said. “Find the right dose that gets them moving but not so much that they're getting chronic watery diarrhea.”

Topicals can also assist in detoxification. Castor bean (Ricinus communis) has been used as a purgative and anti-inflammatory both internally and externally. When used internally, he said, castor bean should only be used in the short-term, as it can irritate the intestinal lining. For external use, Ingels recommended applying a thin layer of the oil over the upper right quadrant (RUQ) of the abdomen, then apply a hot water bottle or heating pad for 15 to 60 minutes, separated from the skin by a sheet of wax or parchment paper.

Essential oils like lemongrass (Cymbopogon citratus), rosemary (Salvia Rosmarinus), and grapefruit (Citrus racemose), can induce detoxication enzymes and have a calming effect on the nervous system. Ingels said he instructs patients to dilute essential oils in a carrier oil such as coconut or avocado oil and use a few drops topically. However, he said he only recommends essential oils be used externally as they can irritate the inside of the body when ingested.  

In addition, specific herbs like dandelion leaf (Taraxacum officinalis), and kava kava (Piper methysticum) can help increase urinary output and improve kidney function. No matter what botanical is being used, Ingels said, detoxification is an ongoing process.

“Lowering the body burden of toxins is still the most important factor,” said Ingels. “We use these plants as a way to help promote you know getting rid of the junk that's already there, but we want to try to curtail the influx of toxins in the first place.”
