Which herb has sedative, anxiolytic, and muscle relaxant actions and is used for insomnia, anxiety, and muscle tension, with contraindications including pregnancy and breastfeeding?

• A. Ulmus rubra (Slippery Elm)
• B. Verbascum thapsus (Mullein)
• C. Valeriana officinalis (Valerian)
• D. Verbena officinalis (Vervain)

Answer: (C)

Valerian fits this profile because it has a well-known sedative, anxiolytic, and muscle-relaxant action that supports insomnia, anxiety, and muscle tension. Its active constituents, valepotriates and valerenic acids, are thought to modulate GABAergic activity in the central nervous system, producing calming effects, improving sleep quality, and reducing muscle tension linked to anxiety. This makes it a classic choice for sleeplessness with restlessness or nervous tension. It’s contraindicated in pregnancy and breastfeeding due to limited safety data and potential risks to the fetus or infant, so it’s generally avoided during these periods. The other herbs listed don’t provide this same combination: Ulmus rubra and Mullein are mainly demulcents with mucilage and do not offer sedative or muscle-relaxant effects, while Vervain is a nervine with mild calming properties but not a robust muscle relaxant, so valerian best matches the described use.
