Herbs for Psoriasis

Calendula (Calendula officinalis), with its bright orange daisy-like flowers, is among the most versatile herbs in Western herbal medicine. Its petals contain antiseptic, anti-inflammatory, and vulnerary properties, making it excellent for speeding tissue repair in wounds, burns, bruises, and various skin irritations. Calendula is also used internally for gastrointestinal inflammation (e.g., Crohn’s disease, colitis, gastritis).

Rehmannia (Rehmannia glutinosa) is a perennial growing to about 1–2 ft (30–60 cm), with sticky leaves and purple tubular flowers. One of the most prized herbs in Traditional Chinese Medicine, it’s considered both cooling (raw) and nourishing (prepared), supporting liver, kidneys, blood, and longevity.

Chinese rhubarb (Rheum palmatum) is a thick-rhizomed perennial, growing up to 10 ft (3 m) tall, with large, palmate leaves and small flowers. Known in Chinese medicine for over 2,000 years, it has a paradoxical effect on the bowels: stimulating in large doses, yet gently astringent and constipating in small doses. The rhizome also aids digestion, helps counter inflammation, and has anti-ulcer and antibacterial actions.

Turmeric (Curcuma longa) is a perennial with a thick rhizome, growing to about 3 ft (90 cm), featuring lance-shaped leaves and pale yellow flowers. Renowned for its bright yellow-orange color, turmeric is a potent anti-inflammatory, antioxidant, and liver-supportive herb commonly employed in Indian cooking and Ayurveda.

Cleavers is a straggling, square-stemmed annual growing to 4 feet with whorls of lance-shaped leaves, clusters of small white flowers, and small round green fruits covered with hooked prickles. The name refers to the plant's ability to cling (or cleave) to fur or clothing. Common throughout Europe and North America and found in many other temperate regions including Australia, it grows prolifically in gardens and along roadsides. The Greek physician Dioscorides in the 1st century CE considered it useful for countering weariness and noted that shepherds used the stems to make sieves for straining milk.
