Ashwattha: Traditional Uses, Evidence & Safety

TL;DR

My take on ashwattha: the peepal tree (Ficus religiosa), sacred in India, used in Ayurveda for ulcers, diarrhea, skin complaints, and diabetes. Every study I found is preclinical: rats and cells, on blood sugar, wounds, inflammation, seizures. No controlled human trials exist in the reviewed literature. Nothing proven in people.

What it is

The peepal tree. If you have spent any time in India you have seen it: huge, spreading, usually near a temple. Botanically it is Ficus religiosa L. of the mulberry family (Moraceae), a large perennial tree across the plains of India, known in English as peepal or pipal (Chandrasekar et al., Pharmacognosy Reviews 2012).

Its Sanskrit name is pippala; asvattha/*ashvattha* turn up among its Bengali and Kannada vernacular names, pipala/*pipal* in Hindi (same review).

And it is the Bodhi tree: the tree under which the Buddha is traditionally held to have attained enlightenment. That gives it a religious weight no pharmacology paper can touch (same review).

The parts used medicinally: bark, leaves, fruits, latex, roots, tender branches.

Traditional use

Traditionally, the bark gets used as antibacterial, antiprotozoal, antiviral, astringent, and antidiarrheal, and in treatment of gonorrhea and ulcers. The leaves: skin diseases, reported antivenom activity, and regulating the menstrual cycle. Over in Bangladesh, the same tree gets used for cancer, inflammation, and infectious diseases. Tender branches as a toothbrush during high fever, fruits as laxatives, latex as a tonic, fruit powder for asthma (Chandrasekar et al., Pharmacognosy Reviews 2012).

Folk use is real and old. None of it has been validated in human studies. I want those two sentences to sit next to each other permanently.

What modern research says

Everything below comes from laboratory or animal work. No controlled human trial of ashwattha was found in the reviewed literature. Read the rest with that sentence in your head.

Blood sugar (animal studies)

Bark extract, given orally at 25, 50, and 100 mg/kg, significantly reduced blood glucose in normal, glucose-loaded, and streptozotocin-diabetic rats. The treated diabetic rats also showed increased serum insulin and liver and muscle glycogen, with reduced serum triglycerides and total cholesterol (Chandrasekar et al., Pharmacognosy Reviews 2012). A compound isolated from the root bark, β-sitosteryl-D-glucoside, showed glucose-lowering effects in diabetic rabbits and rats (same review).

Animal findings only. No human diabetes data. Say it with me.

Wound healing (animal studies)

A hydroalcoholic leaf extract, applied as a 5% and 10% ointment, showed dose-dependent wound-healing activity in rat excision, incision, and burn models: faster wound contraction and epithelialization, greater wound-breaking strength than controls (Chandrasekar et al., Pharmacognosy Reviews 2012). No human wound studies were identified in the reviewed literature.

Inflammation and neuroprotection (animal and cell studies)

An alcoholic bark extract showed immunostimulant properties in mice, improving both cellular and antibody responses (Chandrasekar et al., Pharmacognosy Reviews 2012). A leaf methanol extract inhibited nitric oxide and pro-inflammatory cytokine production in activated microglial cells via the MAPK pathway, which the authors read as a possible neuroprotective mechanism against inflammatory mediators (same review). An aqueous bark extract reduced oxidative stress in experimentally diabetic rats (same review).

Three separate leads. All of them end at the lab door.

Seizures (animal studies)

A methanol extract of the figs showed dose-dependent anticonvulsant activity (25, 50, and 100 mg/kg) against electrically and chemically induced convulsions in mice, with no neurotoxic effect at the tested doses. The effect appeared to involve serotonin-linked pathways (Chandrasekar et al., Pharmacognosy Reviews 2012). Interesting pharmacology. A long way from a human anti-seizure treatment.

Infection (laboratory studies)

Leaf extracts showed antibacterial activity against Staphylococcus aureus, E. coli, Salmonella, and Shigella species, and antifungal effects against Candida albicans. A bark methanol extract was lethal to the parasitic worm Haemonchus contortus in vitro (Chandrasekar et al., Pharmacognosy Reviews 2012). Laboratory findings only. Petri dishes do not cough.

Cholesterol (animal study)

Dietary fiber from the tree (peepalbanti), fed at 10% of the diet, increased resistance to diet-induced hyperlipidemia in rats, apparently by increasing fecal excretion of cholesterol and bile acids (Chandrasekar et al., Pharmacognosy Reviews 2012).

Safety & contraindications

The review contains no safety section at all. That is itself the key safety fact (Chandrasekar et al., Pharmacognosy Reviews 2012).

No systematic toxicity or human safety data were found in the reviewed literature. So: no established safe dose, no human safety record. Treat internal use cautiously. Avoid in pregnancy and breastfeeding. Do not combine with prescription medicines (especially diabetes or seizure drugs, given the animal pharmacology) without clinician guidance.

Traditional use is not evidence of safety. I wish that sentence did not need saying.

FAQs

What is ashwattha?

Ficus religiosa, the peepal or sacred fig: a large Indian tree of the mulberry family, known in Sanskrit as pippala and revered as the Bodhi tree of Buddhist tradition (Chandrasekar et al., Pharmacognosy Reviews 2012). Its bark, leaves, fruits, and latex show up in Ayurvedic and folk practice.

Is peepal the same as ashwattha?

Yes. Peepal (also spelled pipal) is the common Hindi/English name for the same tree, Ficus religiosa. Ashwattha (Sanskrit asvattha) and pippala are its classical names; it is also called the sacred fig and, in Buddhist tradition, the Bodhi tree (Chandrasekar et al., Pharmacognosy Reviews 2012). One species, many names. So herbal products using any of these names refer to the same plant.

Does ashwattha lower blood sugar?

In rats, yes: bark extracts lowered blood glucose and raised insulin in diabetic animals. But no human trial testing ashwattha for blood sugar was identified in the reviewed literature, so there is no basis for using it to treat diabetes in people (Chandrasekar et al., Pharmacognosy Reviews 2012). The rat-to-human jump is where most herbal marketing lives. Do not make it.

Is ashwattha bark safe to take?

Unknown. The pharmacological review found no systematic toxicity or human safety studies of ashwattha. An evidence gap, not a clean bill of health (Chandrasekar et al., Pharmacognosy Reviews 2012). Without safety data, avoid internal use in pregnancy, breastfeeding, and alongside prescription medicines unless a clinician advises otherwise.

Can ashwattha leaves heal wounds?

A hydroalcoholic leaf extract applied as a 5% and 10% ointment sped wound healing in rats: faster wound contraction and epithelialization, greater wound-breaking strength in excision, incision, and burn models (Chandrasekar et al., Pharmacognosy Reviews 2012). Consistent with traditional external use. But animal wound models do not prove the effect in humans, and no human wound studies were identified in the reviewed literature.

Sources

The whole article rests on one paper: Chandrasekar SB et al., "Phytopharmacology of Ficus religiosa," Pharmacognosy Reviews, 2012, volume 6, issue 11, pages 193–199 (full text). It is a review of traditional uses and preclinical pharmacology. Every traditional claim and every animal study cited above comes from it. When I say the evidence is preclinical, this paper is why.
