Nervines

Nervines are herbs and other botanicals traditionally used to support the nervous system. In herbal medicine and related traditions, nervines are a broad category rather than a single pharmacological class. They are employed for symptoms commonly described as nervous tension, anxiety, stress, insomnia, and fatigue, and are often regarded as supporting resilience of the nervous system rather than treating a specific disease.

Nervines are typically divided into two broad groups: nervine relaxants (sedatives) and nervine tonics (nervous-system nutritives). Relaxants are used for short-term calming and sleep-promoting effects, while tonics are believed to strengthen and nourish the nerves over time. Some nervines also function as anti-spasmodics or demulcents, contributing additional actions beyond nervous-system support.

Prominent examples include:

- Nervine relaxants: passionflower (Passiflora incarnata), valerian (Valeriana officinalis), chamomile (Matricaria chamomilla), lemon balm (Melissa officinalis), lavender (Lavandula angustifolia), and skullcap (Scutellaria lateriflora).

- Nervine tonics: milky oats (Avena sativa) preparations, ashwagandha (Withania somnifera), vervain (Verbena officinalis), and other adaptogenic or nutritive herbs used in traditional practice.

Preparation methods commonly used for nervines include teas, tinctures, and standardized extracts, with dosing guided by traditional usage and, when possible, professional advice. Safety considerations vary by herb; some nervines can cause sedation, interact with medications, or have contraindications in pregnancy. As with all herbal remedies, nervous-system use should be discussed with a qualified health practitioner, especially for individuals with medical conditions or those taking other treatments.
