These herbal services is widely accept by the society because it meet their need. People realize that there are some weakness of modern medicine and on the other side there are some advantages of herbal medicine.

The weaknesses of modern medicine / chemical medicine :
a.The side effect.
There are side effects of chemical medicine that can appeared straight away or accumulated. These happened because chemical materials are inorganic and pure material while the body of human being is organic and complex. So chemical material are not the material that really suit to the body. Consumption of chemical materials for the body is considered as 'inevitable' due to the reason that it is very limited consumption that can be accepted and tolerated by the body.

b. Often lack of effectiveness for certain diseases.
Some diseases have no medicine; the medicine used is mainly for symptomatic therapy and should be consumed continually. Some diseases do not found the cause yet. Many patients should go to doctors continually without any significance improvement or even getting worse.

c. The high price due to the import factors. Nearly all chemical medicine we used come from other countries. This happened because to produce medicine we need high technology, a lot of investment and long term research. Other significant reason that influences to import is that medicine production need trustworthy. Up to now the trustworthy is owned by certain countries that are known as medicine producer. That import contents are include: - Medicine, - Medicine raw materials - Medicine packaging - Technology - Equipment and machines - Expert and skill workers. The imports are funded by foreign currencies makes the price high and fluctuated following the exchange rate and also makes the uncertain availability.


Some advantages of herbal medicine:
a. No side effect if it is used in normal dosage
This is because herbal medicine is composed by complex organic substances that suite to the body which is also composed of complex organic substances. In other word herbal medicine can be considered as food that means materials that are consumed in order to reconstruct destroyed organ or system.
Excessive of herbal use certainly create side effects in a same way as excessive food consumed. As a result the key of the dosage recommendation for herbal use is the traditional dosage and a little bit lowered.

b. Effective, even for disease that is difficult to be helped with modern medicine. Based on the inheritance experiences written or oral, and than studied from various aspect such as botany, chemistry and pharmacology. The approached in using herbal medicine is emphasized on the pharmacology aspects which means the function of the herbs in the therapy process.

c. Low price and can be planted personally.
Especially if the modern families can grow medicinal herbs as 'family medicinal herbs garden' that is important for healthcare, disease prevention and curative purposes. The price is increase when if the herb is preserved by drying, and higher when the herb is provided as powder to be consumed as tea or as capsule, and even higher when it is in the form of extract. The highest price is found when it is provided as certain isolate compound such as vincristine and vinblastine as the medicine to cure cancer which is isolated from 'tapak dara' (Catharantus roseus). The use of isolates are considered as chemical medicines.

d. No medical assistant needed.
If the diagnosis is quite clear the therapy can be done at home with the help of the family members. Doctors are needed to give correct diagnosis with the help of clinical laboratory data, therapy recommendation can be given by the doctors but the therapy application is sufficiently done by the family member.
