What Makes Solomon’s Seal (Yu Zhu) Unique?

Most herbs marketed for joints, lungs, or digestion are warming, stimulating, or drying over time. Yu Zhu is different.

Solomon’s Seal is classified in Chinese medicine as a Yin-nourishing, dryness-moistening herb, meaning it helps:

• Restore moisture rather than force stimulation

• Soothe irritated tissues instead of masking discomfort

• Support long-term resilience rather than short-term effects

This makes it especially valuable for people who experience:

• Dry or scratchy throat

• Non-productive or dry cough

• Dry digestion or low stomach fluids

• Tight, under-lubricated joints or sinews

• General dryness from stress, aging, or climate

Traditional Chinese Medicine (TCM) Actions

In TCM, Yu Zhu is traditionally used to:

• Nourish Lung Yin – supports moisture in the respiratory tract

• Nourish Stomach Yin – helps maintain digestive fluids

• Moisten dryness – without creating heaviness or stagnation

• Support sinews and connective tissue – gentle lubrication

Taste & Nature:

• Sweet

• Slightly cold

• Slightly bitter

Meridians Entered:

• Lung

• Stomach

Naturally Occurring Plant Compounds

Solomon’s Seal contains a range of naturally occurring constituents, including:

• Convallarin & Convallamarin – traditionally associated with cardiovascular support

• Allantoin – known for soothing and tissue-supportive properties

• Kaempferol & Quercitol – plant flavonoids

• Azetidine-2-carboxylic acid

• Trace Vitamin A

These components help explain why Yu Zhu has long been valued for soothing, cooling, and restorative applications rather than stimulation.

How Solomon’s Seal Is Traditionally Used

Dry Coughs & Throat Irritation

Yu Zhu is considered demulcent, meaning it coats and soothes irritated tissues. Traditionally used in teas for:

• Dry, raspy, or irritated throat

• Non-productive coughs

• Lung dryness

Joints, Tendons & Ligaments

Solomon’s Seal is well known in multiple herbal traditions for supporting:

• Joint comfort

• Connective tissue hydration

• Tendons and ligaments

This reputation appears in both Chinese medicine and Native American herbal use.

Digestive Dryness

Yu Zhu supports digestive fluids without irritating the stomach, making it suitable for people who experience:

• Dry digestion

• Reduced appetite related to dryness

• Sensitivity to harsher herbs

Taste Profile 

Solomon’s Seal has a mild, slightly sweet, nutty flavor.
It is not bitter or harsh and blends well into teas and soups.

How to Prepare Solomon’s Seal (Proper Use Matters)

Hot Tea (Simple Method)

1. Place ½ teaspoon chopped or lightly ground root in a cup

2. Pour freshly boiled water (wait 1–2 minutes after boiling)

3. Cover and steep 7–10 minutes

Cold Infusion (Best for Dryness)

Cold infusion preserves the demulcent qualities.

1. Add 1 tablespoon sliced root to room-temperature water

2. Cover and steep 7–10 hours

3. Strain and sip throughout the day

This is the preferred method for throat, lung, and digestive dryness.

Traditional & Culinary Use 

Solomon’s Seal rhizomes are naturally rich in starch.

Historically:

• Native American tribes processed the starch to make breads and soups

• Dried root was ground and added to foods as nourishment

This dual use highlights Yu Zhu’s role as both medicine and food.
