COMMON NAME: OAT, oatstraw, milky oat, wild oats, oatgrass, catgrass
LATIN NAME: Avena sativa
FAMILY: Poaceae, Graminaceae
PARTS USED: Milky oat tops; oat stem
REGIONS: throughout the world
SYSTEM AFFECTED: nervous, structural
HARVESTING GUIDELINES: Milky oats are the oat grains harvested when they are in their milky stage, during which the oat grains release a white, milky sap when squeezed. This stage, which lasts approximately one week, occurs after the oat begins flowering and before the seed hardens and becomes the oat grain we eat as oatmeal.
PLANT CONSTITUENTS: saponins, alkaloids (trigonelline and avenine), a sterol, flavonoids, starch, protein (gluten), fats, minerals (including silica, iron, calcium, copper, magnesium, zinc), vitamin B
ACTIONS: Antidepressant, Anxiolytic, Aphrodisiac, Cardiotonic, Demulcent, Emollient, Hypocholesterolemic, Immunomodulant, Nervine, Reproductive tonic, Trophorestorative, Nutritive
TASTE: Slightly sweet,
ENERGY: Cooling, Moistening, warming Oat-straw and milky oats (Avena sativa) have long been used as gentle, restorative botanical for the nervous and reproductive systems. They are commonly credited with these benefits:
USES: Nervine support: Rich in B vitamins, calcium, magnesium, and other nutrients, oatstraw and milky oats are considered nutritive nervines. They may help soothe nervous tension from stress, overwork, emotional trauma, or mild depression and anxiety. Reported symptoms they may ease include irritability, chronic fatigue, poor concentration, reduced libido, and heart palpitations.
- Mood and sleep: Oatstraw infusions and milky-oat tinctures are traditionally used to mellow mood, reduce anxiety, and support restful sleep.
- Reproductive health: Historically, oatstraw has been used to help regulate menstrual cycles and to calm symptoms described as “hysteria” in older texts. Milky oats (immature seed tops) are often used when more acute nervous-system support is desired.
- Bone health: Oatstraw’s mineral content, especially calcium and magnesium, contributes to its reputation for supporting bone strength and may be helpful as part of a broader strategy to prevent osteoporosis.
- Urinary and lymphatic support: Oatstraw is reported to have mild diuretic and anti-inflammatory effects, which can support urinary tract health and reduce edema or lymphatic swelling.
- Skin soothing: Colloidal oat preparations and milky-oat baths release emollient compounds that hydrate and calm irritated skin. They are commonly used for itchy conditions such as poison ivy, chickenpox, and stress-related dermatitis.
- Cardiovascular benefits: Regular use of oats has been associated with cholesterol-lowering effects, largely attributed to oat fiber and associated phytochemicals.
CONTRADICTIONS: Of concern to individuals with celiac disease is the fact that oats are often processed in facilities that also process wheat and other gluten-containing ingredients and may become contaminated with gluten.
DOSAGES: Tincture: 3-5 mL tincture 3x per day
Tea: 1-4 cups of oatstraw infusion per day (1 ounce oat straw in 1 quart boiling water; steep at least 4 hours)
Suggestions for use: oatstraw infusion (tea), milky-oat tincture, or topical colloidal-oat baths.
