Freeze-dried chives, dried coriander leaf and several fresh herbs rank among concentrated sources of vitamin C, although the USDA values are based on 100-gram portions that are far larger than typical culinary servings.

Vitamin C is usually associated with oranges and other fruits, but several common herbs and spices can also contain substantial concentrations of the nutrient, according to USDA FoodData Central figures cited in a March 18, 2026, NaturalNews.com report.
Six products highlighted in the report — freeze-dried chives, dried coriander leaf, fresh thyme, fresh parsley, fresh dill weed and saffron — contain between 80.8 milligrams and 660 milligrams of vitamin C per 100 grams.
The serving size is an important qualification. Herbs and spices are generally eaten in much smaller quantities than 100 grams, meaning a tablespoon or pinch would supply only a fraction of those listed amounts.
Most adults require roughly 90 to 120 milligrams of vitamin C per day to meet established dietary guidelines, according to the nutritional information cited in the report. Vitamin C has recognized roles in normal immune function and also acts as an antioxidant.
Among the six foods, freeze-dried chives had by far the highest concentration, providing 660 milligrams of vitamin C per 100 grams.
Dried coriander leaf, commonly known as cilantro when fresh, ranked second at 567 milligrams.
The source material also identifies chives as containing vitamin A, iron, magnesium and potassium, while coriander leaf supplies potassium and vitamin K.
Both can be incorporated into a range of foods. Chives can be used with potatoes, meats, soups and dairy-based dips, while cilantro works in dishes including soups, stews, salads, salsa and guacamole.
The USDA database specifically lists the products as freeze-dried chives and dried coriander leaf, meaning their vitamin C concentrations should not be assumed to apply directly to equal weights of the fresh herbs.
Fresh thyme followed with 160 milligrams of vitamin C per 100 grams, while fresh parsley supplied 133 milligrams.
Dill weed contained 85 milligrams per 100 grams, and saffron provided 80.8 milligrams.
Beyond its vitamin C content, thyme contains antioxidant compounds and has demonstrated antimicrobial properties, according to the source material. It also has a long history of use in food preservation, including meat curing and pickling.
Parsley has attracted scientific interest for another constituent, apigenin. A separate report cited research published in Cancer Letters indicating that apigenin can inhibit the growth and spread of cancer cells under the conditions studied. Such findings do not by themselves establish that eating parsley prevents or treats cancer in people.
Herbs have occupied a role in both food and traditional medicine for thousands of years. Jordan Rubin wrote in The Maker’s Diet that herbs were among humanity’s earliest medicinal resources and remain sources of nutritional support.
Foods That Harm, Foods That Heal similarly describes fresh and dried herbs as sources of numerous active phytochemicals and notes their historical use as flavorings, medicines, perfumes and dyes, as well as in warfare.
Modern research has also explored whether combinations of herbs and spices can influence metabolic responses to meals. One study highlighted in the source material found that adding a mixture of nine herbs and spices reduced some of the effects associated with an unhealthy meal.
Their antioxidant content is one potential area of interest.
The Gale Encyclopedia of Diets describes antioxidants as compounds that help protect cells from damage caused by molecules known as oxygen-free radicals. Michael Greger’s How Not to Die also lists herbs and spices among foods with antioxidant capacity.
Vitamin C itself is a water-soluble antioxidant with an established biological role in immune function. Researchers have additionally studied vitamin C in connection with acute lung infections, according to a news roundup from ANH International.
In a Brighteon Broadcast News segment, Mike Adams noted that most animals can manufacture vitamin C from glucose, while humans lack an enzyme required to complete that process. Adams has also advocated eating vitamin C-rich fruits with barbecued foods as a dietary measure intended to counter some of the potential risks associated with grilled foods.
How herbs are prepared and stored can affect how much vitamin C ultimately reaches the plate.
Vitamin C is relatively fragile and can degrade during prolonged storage or cooking. Because it is water-soluble, preparation methods that immerse foods in water can also contribute to nutrient losses.
Steaming and microwaving are among the cooking techniques recommended in the source material to limit vitamin C loss compared with boiling or blanching.
A review in the Journal of Food Composition and Analysis found that vitamin retention changes with heat treatment and over time. Guidance on growing, preparing and storing leafy greens similarly emphasizes proper handling and refrigeration to preserve freshness and nutrients.
Sauces, salads and finished dishes that use fresh herbs without prolonged cooking may therefore retain more of their original vitamin C than preparations subjected to extended heat, although the amount consumed still depends heavily on serving size.
The six USDA-listed products provide another way to add vitamin C and other plant compounds to the diet, but their unusually high per-100-gram numbers should be interpreted in context.
Few people consume anything close to 100 grams of dried coriander leaf, freeze-dried chives or saffron at one sitting. Their practical contribution to daily vitamin C intake will generally be much smaller than the headline concentrations suggest.
Used regularly alongside fruits, vegetables and other nutrient-rich foods, however, herbs and spices can contribute additional vitamins, minerals and phytochemicals while adding flavor without requiring large portions.
