JPH1135431A - Extraction of aloe medicinal ingredient and hair grower - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a hair grower containing an aloe medicinal ingredient as the main ingredient, and to provide a method for extracting the aloe medicinal ingredient for affording the above hair grower. SOLUTION: Dried leaf skin afforded by sun-drying or heat-drying the leaf skin peeled off the leaves of aloe vera is immersed in an aqueous ethanol solution to extract the aimed medicinal ingredient; wherein it is recommended that the aqueous ethanol solution is incorporated with 1,3-butylene glycol or propylene glycol (pref. both of them), and as for the drying means, sun-drying or heat-drying process is especially excellent. Extraction of the medicinal ingredient by this method results in high concentration thereof compared to the case with the conventional extraction from the leaves of Aloe arborescens Mill. var. nat or the mesophyll of aloe vera, affording higher medicinal effect. In particular, this hair grower obtained by the present method and containing the above extract afforded by this method has trichogenous action by far excellent compared to conventional ones.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair restorer which is applied to the scalp to prevent thinning of the hair and to promote hair growth. And a method for extracting a medicinal component of aloe for obtaining the hair restorer and the like.

[0002]

2. Description of the Related Art Aloe is known to have medicinal properties such as promoting blood circulation and activating cells. Aloe leaf can be put into a bathtub and used as a bathing agent having a blood circulation promoting effect. BACKGROUND ART Conventionally, health juices and cosmetics having a skin activating effect have been produced by adding juice to juices and cosmetics. The use of medicinal components of aloe as a hair restorer has been conventionally performed, and the medicinal components contained in aloe leaves are extracted with an aqueous solution of ethanol, 1,3-butylene glycol, and propylene glycol, and are used as a main component. I have a hair restorer. By applying the hair restorer thus obtained to the scalp, blood circulation of the scalp is promoted and hair mother cells are activated to prevent thinning hair and promote hair growth.

[0003] Conventionally, as this hair restorer, Kidachivera cultivated in Japan is used, and its leaves are immersed in the above-mentioned ethanol aqueous solution to elute the medicinal components, or it is called aloe vera (scientific name: aloe barbadensis). Aloe leaf having large leaves is soaked in the above aqueous ethanol solution to extract a medicinal component. Aloe vera is grown only in Okinawa in Japan,
The main production areas are the United States and Taiwan. The aloe vera cultivated in these areas has a thick leaf, peels the leaf skin and takes out the leaf, and uses the leaf as a raw material for obtaining a hair restorer, a bath additive, or a juice to be added to juice or cosmetics. Leaf bark is treated as waste in production areas and used as fertilizer and feed.

[0004]

SUMMARY OF THE INVENTION The present invention was made as part of a study aimed at effectively utilizing aloe vera leaves that had been discarded in the past. The objective is to obtain a product with excellent action.

[0005]

The method for extracting the medicinal components of aloe vera according to the present invention is characterized in that the leaf peel peeled off from the leaves of aloe vera is dried in the sun or under heat and the dried leaf peel is immersed in an aqueous ethanol solution. It extracts medicinal ingredients. It is preferable to add 1,3-butylene glycol or propylene glycol, preferably both, to the aqueous ethanol solution, and by adding these, an extract having a higher concentration can be obtained. As a drying method, solar drying or hot air drying is particularly excellent.

The solution containing the components extracted by the above method has excellent medicinal properties as a hair restorer. The hair restorer according to the present invention is mainly composed of a medicinal ingredient extracted by the above method.

[0007]

When the medicinal component is extracted from the leaf skin of aloe vera by the method according to claim 1 or 2, a higher concentration is obtained as compared with the conventional extract from aloe vera leaf or aloe vera leaf, and therefore a higher medicinal effect is obtained. Action is obtained. In particular, it was confirmed that the hair restorer containing the extract solution obtained by this method as a main component has a far superior hair growth effect as compared with conventionally known hair restorers.

[0008] Factors causing hair loss or thinning of the scalp include poor blood circulation of the scalp, reduced vitality of hair matrix cells, and adhesion of excess sebum to the scalp. Poor blood circulation in the scalp causes insufficient nutrients and oxygen to be delivered from the capillaries to the dermal papilla, causing a failure to produce healthy and durable hair. Smooth muscles and mucous membranes are stimulated by components such as valobaroin, isovalobaroin, aloe-emodin, and clinphanol, which are included in the medicinal components of aloe vera extracted according to the present invention, and their activities are enhanced to promote blood circulation.

[0009] When the activity of hair matrix cells decreases, hair loss and hair thinning occur due to a decrease in hair growth activity. Among the medicinal components of aloe extracted by the method of the present invention, aloe mannan, mucin, aloe borane, etc., activate hair matrix cells,
Hair growth and hair growth effects are obtained. In addition, the excess sebum in the scalp causes enzymes in the sebum to reduce male hormones and inhibit the action of hair matrix cells. Sebum in the scalp is secreted higher when improving rough skin. The anti-inflammatory and bactericidal effects of aloe, aloecin, and other components contained in the medicinal components of aloe suppress sebum secretion, prevent hair loss, and promote hair growth.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION A thin wire is laterally moved along the leaf between the leaf skin and the leaf of the collected aloe vera to peel the skin. The peeled peel is exposed to the sun or dried with hot air to obtain a brown dry leaf. Ethanol, 1, 1
(3) The drug is immersed in an aqueous solution of butylene glycol and propylene glycol to extract a medicinal component in the dried leaf skin. At this time, the pH of the aqueous solution is adjusted to 6 to 6.5.

The aqueous solution to be extracted may have the same composition as the aqueous solution used to extract the medicinal components of Kidachivera. It must be at least an aqueous ethanol solution. Usually, at least one, preferably both, of 1,3 butylene glycol and propylene glycol are added to ethanol. Examples of preferred components and concentrations are as follows. Ethanol 30% by weight 1,3 butylene glycol 15% by weight Propylene glycol 15% by weight Water Remaining The solution from which the pharmaceutically active ingredient has been eluted has a dark brown color.

The thus obtained solution containing the medicinal component of the leaf skin of aloe vera is applied to the scalp twice a day after washing the hair at least once, and the fingertip is applied in the same manner as when a conventional hair restorer is used. Massage to rub in. The effect is different depending on the person, but as a result of using it for many people, about one in five people has a remarkable effect. A hair-growth effect was observed.
