Panax Ginseng Benefits: What Asian Ginseng Does, Who It Suits and How to Take It

Written and reviewed by Dr. Michael Koh, Chinese herbal medicine practitioner at The Oriental Herb, Cliffside Park, NJ

Ginseng is the herb everyone has heard of and almost everyone misuses – taken for a quick energy lift by people who would do better with sleep, or avoided by exhausted people who would benefit most. In Chinese medicine Ren Shen (Panax ginseng) is the great Qi tonic, reserved for genuine depletion, and the way it is chosen and dosed matters as much as the herb itself. This guide covers the real panax ginseng benefits, the different types we stock, and who should leave it alone. Energy and fatigue in general are covered on our Chinese herbs for energy page.

What ginseng is for in Chinese medicine

Ren Shen strongly tonifies the Qi of the Spleen and Lungs, generates fluids and calms the spirit. In plain terms: for people who are worn out – after illness, surgery, childbirth, long stress or simply age – with a weak voice, poor appetite, shortness of breath on effort, sweating easily and a pale complexion. It appears in the great tonic formulas: Si Jun Zi Tang, Bu Zhong Yi Qi Tang (see our guide), Sheng Mai San, Gui Pi Tang. It is not a stimulant; the energy it gives is slow and lasting.

What the research says

Panax ginseng has more clinical trials behind it than almost any other herb. The best-supported areas are fatigue (including cancer-related fatigue in several trials), immune function and fewer colds, modest improvements in fasting blood sugar, and small benefits for cognition and mood in older adults. Effects on erectile function and exercise performance are suggestive. The honest summary: real but moderate, and dependent on dose and quality. For the blood sugar side see our blood sugar support page; for cognition, memory and brain health.

Red, white, and American – choosing the right ginseng

• Red ginseng (Hong Shen) – steamed and dried; warmer, stronger, for cold, exhausted people. Korean red ginseng is the best-known form.
• White ginseng (Sheng Shai Shen) – sun-dried; milder, more neutral; better for long-term use in mild deficiency.
• American ginseng (Xi Yang Shen, Panax quinquefolius) – cool in nature, generates fluids; for the tired person who also runs hot, has a dry mouth, night sweats or is recovering from a fever. Often the right choice for New Jersey summers and for people who find Asian ginseng too heating.
• Dang Shen (Codonopsis) – not a Panax but used as a gentle, inexpensive substitute in everyday formulas.

How to take it

Typical doses are 1–3 grams of dried root daily as a decoction or in granules, or 200–400 mg of a standardized extract. Take it in the morning; it can disturb sleep if taken late. Cycle it – three weeks on, one week off, or as the formula directs – rather than taking it indefinitely. Slices of root simmered 20 minutes with a few jujube dates is the simplest traditional preparation.

Who should not take ginseng

People with uncontrolled high blood pressure; anyone with acute infection, fever or a very hot, red, irritable constitution; people on warfarin (ginseng reduces its effect), on MAOIs, or on diabetes medication without monitoring; and pregnant women unless prescribed. Children do not need it. Taken by the wrong person it causes headaches, palpitations, insomnia and irritability – the classic signs that ginseng was not the right herb.

FAQ

Is ginseng good for anxiety?

Not for the tense, wired type – it can worsen it. For anxiety rooted in exhaustion, as part of a formula like Gui Pi Tang, yes. See herbal remedies for anxiety.

Ginseng tea bags from the supermarket?

Usually too weak to matter. Buy root or a standardized extract from a source you trust.

Can I take it every day?

In small doses, for the right person, for defined periods. Ask us which type and how long.
