## Overview

Miner's lettuce (Claytonia perfoliata) is a nutrient-dense wild green containing high concentrations of vitamin C, vitamin A, and omega-3 fatty acids that support [immune function](/ingredients/condition/immune-support) and [skin health](/ingredients/condition/skin-health). Its mucilaginous compounds provide hydration benefits while antioxidants like beta-carotene protect against cellular [oxidative stress](/ingredients/condition/antioxidant).

## Health Benefits

- Supports [immune function](/ingredients/condition/immune-support) with high levels of vitamin C and [antioxidant](/ingredients/condition/antioxidant)s.
- Promotes skin vitality and [collagen synthesis](/ingredients/condition/skin-health) through vitamin A.
- Contributes to bone strength and clotting function via vitamin K and calcium.
- Aids in hydration and digestion due to its high water content.
- Offers mild detoxification and cellular protection through antioxidant compounds. Additionally, the nutritional profile of Miner's Lettuce (Claytonia perfoliata) includes - vitamin c: boosts immunity and enhances skin health through collagen support. For enhanced efficacy, Miner's Lettuce (Claytonia perfoliata) can be combined with complementary ingredients. Hermetica Synergy Stack (Formulation Heuristic)
Role: Mineral + chlorophyll base (systemic vitality)
Intention: Immune & [Inflammation](/ingredients/condition/inflammation) | Gut & [Microbiome](/ingredients/condition/gut-health)
Primary Pairings: Watercress; Chickweed; Lamb’s Lettuce (Valerianella locusta)
Evidence: see study_urls / reference_urls

## Mechanism of Action

Miner's lettuce delivers vitamin C that enhances neutrophil function and stimulates interferon production for [immune support](/ingredients/condition/immune-support). Beta-carotene converts to retinol, promoting [collagen synthesis](/ingredients/condition/skin-health) via fibroblast activation. Mucilaginous polysaccharides form protective gel barriers in the digestive tract, enhancing water retention and nutrient absorption.

## Clinical Summary

Limited clinical research exists specifically on Claytonia perfoliata supplementation. Traditional use studies and nutritional analyses confirm high vitamin C content (80-120mg per 100g fresh weight) comparable to citrus fruits. Preliminary phytochemical studies identified omega-3 fatty acids and phenolic compounds, but controlled human trials examining therapeutic dosages are lacking. Current evidence relies primarily on traditional ethnobotanical use and nutritional composition data.

## Nutritional Profile

- Vitamin C: Boosts [immunity](/ingredients/condition/immune-support) and enhances [skin health](/ingredients/condition/skin-health) through collagen support.
- Vitamin A: Supports vision, skin renewal, and immune defense.
- Vitamin K: Essential for bone [metabolism](/ingredients/condition/weight-management) and blood clotting.
- Iron: Vital for [energy production](/ingredients/condition/energy) and preventing anemia.
- Flavonoids & Carotenoids: Provide [antioxidant](/ingredients/condition/antioxidant) and [anti-inflammatory](/ingredients/condition/inflammation) benefits.

## Dosage & Preparation

Recommended Dosage: Tea: Steep 1-2 teaspoons of dried leaves in hot water for 5-10 minutes, drink 2-3 cups daily. Powder: Mix 1-2 teaspoons (2-5g) into smoothies or beverages. Fresh: Add to salads, soups, or cooking.

Traditional Use & Preparation: - Fresh: Eat raw in salads, wraps, or as a garnish to elevate hydration and nutrient density.
- Smoothies: Blend with citrus or berries for a refreshing, [antioxidant](/ingredients/condition/antioxidant)-rich drink.
- Soups: Stir in near the end of cooking to retain nutrients and texture.
- Tea: Lightly steep fresh leaves to create a mild herbal infusion that supports skin and immune health.

General Guidance: Start with a lower dose and increase gradually. Consult a healthcare provider before starting any new supplement, especially if pregnant, nursing, or taking medications.

## Safety & Drug Interactions

Miner's lettuce is generally recognized as safe when consumed as food with no reported serious adverse effects. High oxalate content may contribute to kidney stone formation in susceptible individuals. No known drug interactions have been documented, though high vitamin K content may theoretically affect warfarin therapy. Pregnancy and breastfeeding safety data is insufficient, though traditional food use suggests low risk.

## Scientific Research

Scientific evidence supports the nutrient density and antioxidant properties of Miner's Lettuce, particularly for vitamin C, carotenoids, and polyphenols. Studies emphasize its role in [immune modulation](/ingredients/condition/immune-support) and [oxidative stress](/ingredients/condition/antioxidant) reduction. See PMC6073502; PMC6464262; PMC5328287.

## Historical & Cultural Context

Revered as a survival plant during the Gold Rush, Miner's Lettuce is now appreciated for its hydrating, cleansing, and revitalizing properties. It is a gentle yet potent reminder of nature’s seasonal nourishment.

## Frequently Asked Questions

### How much vitamin C is in miner's lettuce compared to oranges?

Miner's lettuce contains 80-120mg of vitamin C per 100g fresh weight, which is significantly higher than oranges at approximately 53mg per 100g. This makes it one of the richest plant sources of vitamin C available.

### Can miner's lettuce help with dehydration?

Yes, miner's lettuce has extremely high water content (90-95%) and contains mucilaginous compounds that help retain moisture in tissues. These properties make it traditionally valued for maintaining hydration, especially in wilderness survival situations.

### What omega-3 fatty acids are found in miner's lettuce?

Miner's lettuce contains alpha-linolenic acid (ALA), the plant-based omega-3 fatty acid, in concentrations of approximately 300-400mg per 100g fresh weight. This contributes to its anti-inflammatory properties and cardiovascular benefits.

### Is miner's lettuce safe for people taking blood thinners?

Miner's lettuce contains vitamin K which may theoretically interact with warfarin and other blood thinning medications. Individuals on anticoagulant therapy should consult their healthcare provider before consuming large amounts regularly.

### How should miner's lettuce be prepared to maximize nutritional benefits?

Miner's lettuce is best consumed fresh and raw to preserve its high vitamin C content, which degrades with heat and cooking. Adding it to salads or consuming within hours of harvesting maximizes nutrient retention and bioavailability.

### Is miner's lettuce safe for pregnant women and nursing mothers?

Miner's lettuce is generally safe for pregnant and nursing women as a food source, providing beneficial vitamins like folate and vitamin K that support fetal development and milk production. However, pregnant women should consult their healthcare provider before using concentrated supplements, as high doses of certain nutrients may require individualized guidance. As with any dietary change during pregnancy or lactation, moderation and professional medical oversight are recommended.

### Can children safely consume miner's lettuce as part of their diet?

Yes, miner's lettuce is safe for children and can be a nutritious addition to their diet, offering essential vitamins and minerals for growth and development. Its mild flavor and tender texture make it suitable for introduction as part of age-appropriate solid foods. Parents should introduce it gradually like any new food and monitor for any individual sensitivities, though allergic reactions are rare.

### What clinical evidence supports the antioxidant and detoxification claims for miner's lettuce?

Miner's lettuce contains documented antioxidant compounds including vitamin C, beta-carotene, and polyphenols that help neutralize free radicals and support cellular protection. While laboratory studies confirm its antioxidant capacity, large-scale human clinical trials specifically measuring detoxification effects remain limited. Most evidence supporting its health benefits comes from its nutrient profile and traditional use rather than extensive randomized controlled trials.
