Native American herbalists reportedly used wild lettuce varieties native to North America for similar purposes, incorporating the plant into ceremonial preparations and daily wellness practices. Documentation from early European settlers indicates they learned about local lettuce applications from indigenous peoples and subsequently integrated these plants into their own medicinal practices. This cross-cultural adoption demonstrates the plant's practical utility and the transferability of herbal knowledge across different traditions.

Historical preparation methods varied considerably by region and tradition. Some practitioners favored fresh juice extracted directly from the plant during harvest season, while others dried the entire aerial parts for storage and year-round use. Herbal wine preparations, tinctures made with alcohol extraction, and simple decoctions represented common approaches documented in historical texts. These varying methods suggest that traditional users recognized different preparation techniques could be optimized for different applications and circumstances.

Victorian-era herbalism saw increased documentation of wild lettuce applications, with detailed descriptions appearing in published materia medica texts and apothecary references. Practitioners of this period created formulations combining wild lettuce with complementary herbs like passionflower, valerian, and chamomile for enhanced effects. This tradition of combination formulations continues in contemporary herbal practice, with many modern preparations featuring wild lettuce as one component within carefully designed blends.

Practical Takeaway: Exploring how different cultures have utilized wild lettuce across centuries reveals patterns in application that can inform contemporary understanding of the plant's potential uses. Recognizing that multiple preparation methods exist empowers individuals to investigate approaches that might align with their specific needs and preferences.
