Rosemary (Rosmarinus officinalis)

Ginkgo (Ginkgo biloba) is a distinctive, long-lived deciduous tree that can grow up to about 100 ft (30 m). It has fan-shaped leaves with radiating veins, often turning bright yellow in autumn. Ginkgo is widely revered for its benefits to circulation, especially in the brain, where it can help improve memory, concentration, and support cognitive function.

Bacopa, also known as Water Hyssop or Brahmi, is a creeping succulent perennial that can grow to about 20 inches. It features spatula-shaped fleshy leaves and pale blue or white flowers on slender stalks. Thriving in marshlands and along the edges of mangrove swamps in warmer temperate and tropical climates - especially southern Asia - it develops into dense mats on mudflats. This herb has been a cornerstone of Ayurvedic medicine for supporting cognitive function and treating various nervous system disorders, and it is increasingly recognized in Western herbalism for its brain-enhancing properties.

Butcher’s broom is a bushy, evergreen perennial that can reach about 3 ft (1 m) in height. It has stiff, leaf-like branches ending in a sharp spine, with small greenish-white flowers and shiny red berries in autumn. Traditionally noted for its tonic effect on the vascular system, butcher’s broom helps prevent blood clots and supports the tone of arteries and veins. It is often recommended for varicose veins, hemorrhoids, phlebitis, and bruises.

White peony is an upright perennial growing to 6.5 feet with large white flowers and divided, dark green leaves. Its history of medicinal use in China stretches back at least 1,500 years, most notably as one of the herbs in 'Four Things Soup,' a renowned female tonic. Traditionally, it is believed that women who take the herb regularly become as radiant as the flower itself. The plant is cultivated throughout northeastern China and Inner Mongolia, propagated from seed in spring or from root cuttings in winter. The root of 4- or 5-year-old plants is harvested in spring or autumn and valued as a hormonal tonic.

Garlic (Allium sativum) is a bulbous perennial in the onion family, recognized for its sharp flavor and characteristic odor. Highly valued for both culinary and medicinal purposes, crushed fresh garlic contains allicin, which has potent antibiotic, antifungal, and antiviral properties. Regular garlic intake supports immunity, respiratory health, and circulatory function.

Gotu kola (Centella asiatica), also known as Hydrocotyle asiatica, is a creeping perennial reaching up to about 20 in (50 cm). It sports fan-shaped leaves, often used in salads across parts of India. Traditionally prized for promoting wound healing and improving nervous system function, it is considered both a cleansing herb for the skin and a reviving tonic for cognitive and nervous issues.

Horse chestnut (Aesculus hippocastanum) is a large, stately deciduous tree growing up to about 80 ft (25 m), known for its palmate leaves and prickly green seed pods that contain shiny brown seeds (“conkers”). The seeds, bark, and leaves contain compounds that strengthen veins and reduce fluid retention, making horse chestnut a leading remedy for varicose veins and poor venous circulation.

Licorice (Glycyrrhiza glabra) is a tall, woody-stemmed perennial reaching about 6½ ft (2 m), with dark green leaves and cream-to-mauve pea-like flowers. Its root, sweetened by glycyrrhizic acid (up to 50 times sweeter than sugar), has a powerful anti-inflammatory action, offering relief in respiratory, digestive, and even arthritic conditions. Licorice is widely used in Chinese, European, and Western herbal medicine.
