Red Vine Leaf

The autumn-harvested leaf of the common grape vine, used in European herbal tradition and available as a standardized extract in supplement markets.

Last reviewed: February 9, 2026

Overview

Red vine leaf comes from Vitis vinifera — the same grape vine that produces wine grapes, table grapes, and raisins. The "red" refers not to a different species but to the leaves harvested in autumn after they have turned from green to deep red, a color change driven by the accumulation of flavonoid and anthocyanin pigments. In Mediterranean and European traditions, grape leaves have long been a culinary ingredient (stuffed grape leaves, or dolma, are a staple across the eastern Mediterranean). The herbal use of the autumn-red leaves is a more specific tradition, concentrated in French and Central European herbalism, where the colored leaves are the starting material for extracts and teas.

This page provides educational context on red vine leaf's identity, traditional background, and safety considerations.

What it is

Red vine leaf refers to the autumn-harvested, pigment-rich leaves of Vitis vinifera, processed for herbal or supplement use. It may appear as:

dried leaves for brewing as tea or infusion
standardized extract in capsule or tablet form (often standardized to flavonoid or anthocyanin content)
topical gel or cream formulations containing red vine leaf extract
a component of herbal blends marketed in the context of leg comfort and circulatory wellness

The distinction between a generic grape leaf and a red vine leaf product lies in the harvest timing. Autumn leaves contain a different pigment and polyphenol profile than green summer leaves, and the herbal tradition specifically values the red-stage chemistry.

Traditional use (educational)

Red vine leaf has a focused but well-documented folk record:

in southern France, vineyard workers historically collected and used autumn grape leaves, and the folk association between red vine leaves and leg comfort became part of regional herbal tradition
French phytotherapy has given red vine leaf extract specific attention; it is among the herbal products available in French pharmacies
the broader Mediterranean use of grape leaves in cooking (dolma, sarma) connects the plant to a culinary identity, though the herbal tradition focuses on the autumn-red leaves rather than the green culinary ones
some Central European herbal traditions also reference red vine leaf, particularly in the context of leg heaviness discussions

These references describe cultural and historical use patterns, not proven clinical outcomes.

What research says

Red vine leaf extract has been studied in a small number of clinical trials, mostly conducted in Europe and focused on the standardized extract AS 195. These trials examined the extract in the context of leg comfort and heaviness. Published results have been cautiously noted by reviewers — some trials reported modest findings relative to placebo, while others noted limitations in study design and duration. The evidence base is more developed than for many folk botanicals but remains thin by the standards of mainstream clinical evaluation. Research has focused on the standardized extract, not on simple leaf tea or non-standardized preparations.

Safety & interactions

Common safety considerations include:

red vine leaf tea consumed in typical beverage amounts is generally considered safe, consistent with the long culinary and herbal history of grape leaves
standardized extracts concentrate specific compounds and represent a different exposure profile than simple leaf tea
side effects reported in clinical trials have been mild and infrequent, primarily gastrointestinal in nature
interactions with medications are not well-documented, reflecting limited formal research rather than established safety

Who should be cautious

Caution is commonly advised for:

individuals with known allergies to grape or Vitis species
pregnant or breastfeeding individuals (formal safety data for concentrated extracts is insufficient, though culinary grape leaf consumption is widespread)
people taking anticoagulant medications (some grape-derived polyphenols have been discussed in anticoagulant interaction contexts, though clinical documentation specific to red vine leaf is sparse)
anyone using concentrated extract products who assumes equivalence with simple grape leaf tea — the chemical profiles differ

Quality & sourcing considerations

Quality factors often discussed include:

harvest timing is the defining quality factor — leaves collected during the red autumn phase contain the pigment and polyphenol profile that distinguishes the herbal product from generic grape leaf
standardization to specific flavonoid or anthocyanin content is the primary marker for extract products
species identification matters — Vitis vinifera is the grape vine of herbal tradition, and products derived from other Vitis species may have different chemistry
the distinction between dried-leaf tea products and concentrated standardized extracts is important for understanding both potency and safety profile

FAQs

Is red vine leaf the same as a grape leaf? Botanically, yes — both come from Vitis vinifera. The herbal product specifically uses leaves harvested in autumn after they have turned red, which alters the chemical profile compared to the green leaves used in cooking.
Is this related to wine or grape seed extract? Red vine leaf, grape seed extract, and wine all originate from Vitis vinifera but involve different plant parts, different processing, and different chemical compositions. They are related by species but distinct as products.
Is this page recommending red vine leaf? No — this is educational information only.
