Christopher Hobbs:
“Lemon juice is taken internally for liver congestion, hyperacidity, hiccoughs, and obesity. Mixed in hot water, it is drunk for colds with fever and sore throat as well as dizziness. It combines well with sage tea and a teaspoon of honey for sore throats. Lemon juice may be applied externally for sunburn and warts. In traditional medicine lemons were used for scurvy, urinary gravel, and venous problems such as varicose veins and hemorrhoids.
Lemon has a taste of SOUR and a temperature of COOL.”
Historical Uses
Lemon has been valued for centuries as a remedy and food, used historically for scurvy due to its high vitamin C content, as well as for fevers, coughs, sore throats, and digestive problems. In traditional Mediterranean and Asian medicine, lemon juice and peel were employed as purifiers and antiseptics.
Modern Clinical Uses
Today, herbalists and naturopaths use lemon for its antioxidant, digestive, and immune-supportive properties. Lemon juice is frequently recommended for its alkalizing effect on the body, helping with digestion, and reducing inflammation. Lemon essential oil is used in aromatherapy to uplift mood, ease stress, and stimulate mental clarity.
Chemistry
Lemons are rich in citric acid, ascorbic acid (vitamin C), flavonoids (hesperidin, diosmin), limonene, and other essential oils. The flavonoids and vitamin C are powerful antioxidants, while citric acid aids in mineral absorption and may support kidney health.
Pharmacology
Lemon’s pharmacological actions include antioxidant, anti-inflammatory, and antimicrobial effects. The compounds in lemon help scavenge free radicals, inhibit microbial growth, and promote the production of collagen, a protein essential for skin and tissue health. Limonene in the essential oil also has anti-cancer, mood-enhancing, and anti-anxiety properties.
Clinical Trials
Lemon and its constituents have been studied in trials primarily for their antioxidant, anti-inflammatory, and metabolic effects. Some studies have found that lemon juice may help reduce blood pressure, improve lipid profiles, and aid weight loss when combined with a healthy diet. Lemon essential oil has also shown potential in reducing anxiety and depression symptoms when inhaled.
Summary
Lemon offers both traditional and evidence-based health benefits, from immune support to mood enhancement. While generally safe, it should be used with consideration for potential dental and skin sensitivity.

Cautions
Lemon is generally safe for most people in normal dietary amounts. Excessive lemon intake, however, can erode dental enamel due to its high acidity. For lemon essential oil, direct application to skin may cause irritation or photosensitivity, especially with exposure to sunlight. Allergic reactions are rare but possible.
