FAQ - Yahom

What is the recommended method for taking Mowaan’s Yahom?

Mowaan’s Yahom may be taken in three recommended ways, as follows:

1. Traditional method of administration

Place the medicine in a mortar or cup and add boiled water or drinking water at room temperature, just enough to cover the pills. Gently crush until dissolved, then drink. This is considered the most effective method, as it provides a refreshing sensation that promotes relaxation and supports improved blood circulation.

2. Chew and swallow, followed by boiled water or drinking water at room temperature.
This method is suitable when time is limited or when it is not convenient to prepare the medicine using the first method. Although the medicine may have a slightly bitter taste, chewing it thoroughly before swallowing allows it to break down and take effect more quickly than swallowing the pills whole.

3. Swallow whole, taken with boiled water or drinking water at room temperature.
This method is suitable for individuals who have difficulty chewing medicine. However, it does not provide the refreshing sensation that is a distinctive characteristic of Ya Hom, which helps promote relaxation and improve blood circulation.


How is Mowaan’s Yahom different from other Yahom formulas?

Yahom refers to herbal medicines that incorporate aromatic ingredients. According to traditional Thai medical theory, aromatic and cooling flavors possess properties that nourish and support the heart. Such ingredients include flower pollens, agarwood, khon dok, kalamphak, saffron grass, civet, Himalayan civet, and others.

Each Yahom formula is designed with distinct therapeutic purposes. When aromatic ingredients are incorporated in proportions sufficient to exert effects related to the wind element (lom), the term Yahom is placed before the name of the formula. Accordingly, Mowaan offers four distinct Yahom formulations, each with different therapeutic properties; however, all share one common benefit: nourishing and supporting the heart.

Mowaan’s Yahom is prepared using traditional aromatic ingredients and classical methods in order to achieve its intended therapeutic properties. Unlike many conventional Yahom preparations, which are commonly in powdered form, Mowaan’s Yahom is presented in pill form. This reflects an adaptation made during Mowaan’s era, when Western medicine began to play a greater role. To remain accessible and practical, Mowaan reformulated traditional Thai medicines into ready-to-use forms, including pills and liquid preparations, making them easier to take and more convenient to carry.

Mowaan’s Yahom does not require mixing with a separate herbal vehicle, such as scented floral water, prior to consumption, as this component is already incorporated into the pills during the manufacturing process. It may be taken with drinking water at room temperature, without the need for hot water, ensuring greater ease and convenience of use.

Why is Mowaan’s Yahom gold-leaf coated?

Gold is regarded as a medicinal substance in traditional Thai medicine. In this discipline, medicinal ingredients are classified into three categories: botanical materials, animal-derived materials, and mineral substances. Gold leaf is therefore classified as a mineral substance, as it is derived from a mineral element.

Gold leaf is traditionally valued for its cooling properties. It is used to help relieve restlessness and sudden startle during sleep, to nourish and enhance the complexion, and is also regarded as a rejuvenating remedy (ya ayuwatthana).

In addition to enhancing the medicine’s intended therapeutic properties, the application of gold leaf also carries symbolic meaning, signifying a medicine prepared as an offering for royalty or persons of high esteem.


The gold leaf applied to the pills is made of pure gold and is therefore safe for consumption. This differs from synthetic gold leaf, which may contain heavy metals and is commonly used for gilding Buddha images.

Why is Mowaan’s Yahom priced at a premium?

A number of ingredients used in Mowaan’s Yahom formulations are rare and, in some cases, imported from overseas, resulting in higher production costs. These include saffron, Terengganu borneol, civet, Himalayan civet, ambergris, tiger milk mushroom, Korean ginseng, and Kulika.

1. Kulika refers to gallstones (or calculi) found in the gallbladder of a langur. It is considered cooling in nature and is traditionally used to counteract heat-related toxins, malignant poisons, and various forms of toxicity. It is also believed to dispel severe phlegmatic obstruction constricting the throat in critically ill patients nearing death.

The estimated value is THB 1.2 million per kilogram.

2. Khorok refers to gallstones found in the gallbladder, bile ducts, or liver of cattle or buffalo. It is traditionally used to relieve thick or viscous saliva, dispel severe phlegmatic obstruction (salet hang wua), and strengthen vitality.

The estimated value is THB 650,000 per kilogram.

3. Terengganu Borneol is derived from the Borneo camphor tree found in the state of Terengganu. It is traditionally used to promote perspiration, expel phlegm, stimulate respiration, activate mental alertness, and support heart function. It is also valued for calming restlessness and relieving wind-related dizziness, lightheadedness, and faintness.

4. Tiger Milk Mushroom is traditionally believed to form from the milk of a nursing tigress that drips onto the ground, where the mushroom subsequently emerges. It is collected from montane rainforests and is valued in traditional practice for relieving fatigue and weakness, easing coughs, and strengthening overall vitality.

5. Saffron is derived from the female stigmas of the saffron flower, with only three threads produced by each blossom. Approximately 160,000 flowers are required to yield one kilogram of saffron. Owing to its rarity and labor-intensive harvesting process, saffron is valued more highly than gold and is traditionally regarded for its heart-nourishing properties.

6. Ambergris is a substance traditionally believed to originate from the spermatic secretion of whales. It has a slightly oily taste with a mild musky note. In traditional Thai medicine, it is valued for correcting imbalances of the wind element and the water element, strengthening vitality, and supporting sexual vigor.
