Palankya (Spinach) in Ayurveda: Properties & Everyday Use

In short

Palankya, known as spinach in English and palak in Hindi, is a familiar part of the Indian kitchen. Classical Ayurveda describes it as astringent and sweet in taste, heavy in quality, and cooling by nature. Spinach is cooked as greens and in dal.

In your kitchen

  • It is cooked into palak dal and saag.
  • As a cooling food, tradition leans on it more in the warmer months.

Good to know

In everyday food amounts it is part of ordinary home cooking. If you're pregnant, nursing or take regular medication, check with your doctor before using it beyond normal food amounts.

What it is

Palankya is the Ayurvedic name for spinach, botanically Spinacia oleracea Linn., an annual leafy vegetable of the goosefoot family (Chenopodiaceae). Sanskrit synonyms include Paalankikaa and Chhurika; it is Palak in Hindi. The leaves are the part used, both as food and as medicine. Classical Ayurvedic texts group it among vegetable drugs (shaka varga), and it is equally familiar to Unani and Siddha practice, where it is known as Paalak and Vasaiyila-keerai respectively (Spinacia oleracea: pharmacognostic and pharmacological overview, IJRAP 2010).

Classical properties

Traditional use

Ayurvedic and allied traditions describe spinach as sweet, cooling, laxative, and diuretic. Traditional applications recorded in the literature include urinary disorders, constipation, anemia, respiratory complaints, fever, and disorders attributed to blood and bile: the leaves being considered refrigerant, demulcent, and mildly laxative. These are traditional food-medicine uses and should not be mistaken for clinical proof that spinach treats any disease (IJRAP 2010 review; The Pharma Journal review, 2022).

What research has looked at

Blood pressure and blood-vessel function

In a randomized, controlled crossover trial in 30 healthy adults, a single spinach meal (nitrate-rich) raised plasma nitric-oxide markers, improved flow-mediated dilation of the brachial artery (a measure of endothelial function), and lowered systolic blood pressure and pulse pressure compared with a low-nitrate control meal (acute human RCT, Free Radical Biology & Medicine). The effect is attributed to dietary nitrates converting to nitric oxide, which relaxes blood vessels: but this was a single-meal study, not evidence that spinach treats hypertension.

Blood pressure and exercise with spinach extract

In a double-blind crossover trial, 11 healthy men took a nitrate-rich red spinach extract for 15 days: resting systolic blood pressure fell, exhaled nitric oxide rose, and time to exhaustion in high-intensity exercise increased versus placebo (human RCT, reported in SpringerProfessional). Small and short-term, this supports a nitrate mechanism but not a disease claim.

Eye health (macular pigment)

In a pilot study, 11 healthy adults ate lutein-rich spinach for two months: macular pigment optical density and blood lutein concentrations rose from baseline (uncontrolled pilot, Nippon Ganka Gakkai Zasshi, 2016; PubMed PMID 26950968). However, a separate 8-week pilot trial comparing spinach powder with carrot juice found no overall significant change in macular pigment, though people whose blood lutein rose the most did gain pigment: so the eye-health evidence is genuinely mixed (British Journal of Nutrition pilot studies).

Safety notes

As an ordinary food, spinach is safe for most people. The main caution concerns warfarin (a blood-thinning medicine): spinach is rich in vitamin K, which opposes warfarin's effect, and NHS-linked anticoagulation guidance advises keeping vitamin K intake steady and consulting the anticoagulation clinic or doctor before making sustained dietary changes (NHS anticoagulation patient leaflet). People prone to kidney stones are often advised about high-oxalate greens, though specific guidance should come from their clinician. Safety data for concentrated spinach extracts or medicinal doses is limited: talk to a clinician before therapeutic use.

FAQs

Is spinach good for anemia?

Traditionally the leaves are used in anemia, and spinach does contain iron and folate. But no clinical trial has tested spinach as an anemia treatment, and plant iron is less well absorbed than meat iron. Treat the traditional use as historical; confirmed anemia needs proper diagnosis and treatment. (IJRAP 2010 review)

Can spinach lower blood pressure?

Short-term human trials show nitrate-rich spinach can acutely lower systolic blood pressure and improve vessel function in healthy people. These are small, brief studies: not evidence that spinach treats hypertension or replaces blood-pressure medication. (Free Radical Biology & Medicine RCT)

Is spinach good for the eyes?

Possibly, through its lutein content. One small pilot found two months of lutein-rich spinach raised macular pigment, but another pilot trial found no overall effect. Evidence is mixed and preliminary: spinach is a reasonable lutein source, not a proven vision treatment. (PubMed PMID 26950968)

Should I eat spinach raw or cooked?

Trials have used frozen, powdered, and fresh spinach with varying results, and no study has directly compared raw versus cooked spinach for health outcomes. Both forms supply nitrates, lutein, and folate; choose the form you will eat regularly.

Can I eat spinach while on warfarin?

Yes, but keep your intake steady. Sudden large increases in vitamin-K-rich greens like spinach can reduce warfarin's effect, so NHS guidance says to maintain a consistent diet and speak to your doctor or anticoagulation clinic before making big changes. (NHS anticoagulation patient leaflet)

Is spinach safe during pregnancy?

As a normal food in culinary amounts, spinach is safe and nutritious in pregnancy. Concentrated spinach extracts or medicinal doses have no pregnancy safety data, so therapeutic use should be avoided unless a qualified practitioner advises otherwise.
